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 March 31, 2021, the Partnership had a portfolio of 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 March 31, 2021, affiliates of the General Partner, including its directors and executive officers and their affiliates, owned ​ 2021 Events ​ Amended Credit Agreement 6, 2024. See Note 7 for additional information. ​ Series B Preferred Unit Offering B Preferred Unit in an offering registered under the Securities Act of 1933. See Note 13. ​ COVID-19 Pandemic —The COVID-19 pandemic continues to make its presence felt at home, in the office workplace and at the Partnership’s retail sites and terminal locations. The Partnership remains active in responding to the challenges posed by the COVID-19 pandemic and continues to provide essential products and services while prioritizing the safety of its employees, customers and vendors in the communities where the Partnership operates. ​ Basis of Presentation ​ The accompanying consolidated financial statements as of March 31, 2021 and December 31, 2020 and for the three months ended March 31, 2021 and 2020 reflect the accounts of the Partnership. Upon consolidation, all intercompany balances and transactions have been eliminated. ​ The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial condition and operating results for the interim periods. The interim financial information, which has been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), should be read in conjunction with the consolidated financial statements for the year ended December 31, 2020 and notes thereto contained in the Partnership’s Annual Report on Form 10-K. The significant accounting policies described in Note 2, “Summary of Significant Accounting Policies,” of such Annual Report on Form 10-K are the same used in preparing the accompanying consolidated financial statements. ​ The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results of operations that will be realized for the entire year ending December 31, 2021. The consolidated balance sheet at December 31, 2020 has been derived from the audited consolidated financial statements included in the Partnership’s Annual Report on Form ​ Noncontrolling Interest ​ The Partnership acquired a 60% interest in Basin Transload, LLC (“Basin Transload”) on February 1, 2013. In connection with the terms of an agreement between the Partnership and the minority members of Basin Transload on September 29, 2020, the Partnership acquired the minority members’ collective ​ 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 financial statements for the three months ended March 31, 2020. ​ 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. The uncertainty surrounding the short and long-term impact of COVID-19, including the inability to project the timing of an economic recovery, may have an impact on the Partnership’s use of estimates. 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 credit losses, (v) assumptions used to evaluate goodwill, property and equipment and intangibles for impairment, (vi) environmental and asset retirement obligation provisions, and (vii) weighted average discount rate used in lease accounting. Although the Partnership believes its estimates are reasonable, actual results could differ from these estimates. ​ Concentration of Risk ​ 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. However, the COVID-19 pandemic has had a negative impact on gasoline demand and the extent and duration of that impact remains uncertain. 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 periods presented: ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ ​ March 31, ​ ​ 2021 2020 Gasoline sales: gasoline and gasoline blendstocks (such as ethanol) 62 % 67 % Distillates (home heating oil, diesel and kerosene) and residual oil sales 33 % 29 % Crude oil sales and crude oil logistics revenue 1 % — % Convenience store sales, rental income and sundries ​ 4 % 4 % Total 100 % 100 % ​ The following table presents the Partnership’s product margin by segment as a percentage of the consolidated product margin for the periods presented: ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ ​ March 31, ​ ​ 2021 2020 Wholesale segment 18 % 3 % Gasoline Distribution and Station Operations segment 79 % 93 % Commercial segment ​ 3 % 4 % Total 100 % 100 % ​ See Note 14, “Segment Reporting,” for additional information on the Partnership’s operating segments. ​ None of the Partnership’s customers accounted for greater than 10% of total sales for the three months ended March 31, 2021 and 2020.

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. ​ 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. 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. The Partnership had no significant contract liabilities at both March 31, 2021 and December 31, 2020.

Net Income Per Common Limited Partner Unit
Net Income Per Common Limited Partner Unit	Note 3. Net (Loss) Income Per Common 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 March 31, 2021 and December 31, 2020 excludes 26,896 and 29,383 common units, respectively, held on behalf of the Partnership pursuant to its repurchase program (see Note 12). These units are not deemed outstanding for purposes of calculating net income per common limited partner unit (basic and diluted).

Inventories
Inventories	Note 4. 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 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ ​ 2021 2020 Distillates: home heating oil, diesel and kerosene ​ $ 211,901 ​ $ 206,177 ​ Gasoline ​ 154,947 ​ 98,747 ​ Gasoline blendstocks ​ 38,143 ​ 27,468 ​ Crude oil ​ 5,177 ​ 6,181 ​ Residual oil ​ 32,507 ​ 21,159 ​ Renewable identification numbers (RINs) ​ 4,237 ​ 2,332 ​ Convenience store inventory ​ 21,890 ​ 22,329 ​ Other ​ 39 ​ 39 ​ Total ​ $ 468,841 ​ $ 384,432 ​ ​ 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 and suppliers may draw inventory from the Partnership. Positive exchange balances are accounted for as accounts receivable and amounted to 31, 2020, respectively. Negative exchange balances are accounted for as accounts payable and amounted to 31, 2020, respectively. Exchange transactions are valued using current carrying costs.

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 ​ 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.

Debt and Financing Obligations
Debt and Financing Obligations	Note 7. 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 $1.17 billion senior secured credit facility (the “Credit Agreement”). On May 5, 2021, the Partnership and certain of its subsidiaries entered into a fifth amendment to the Credit Agreement which, among other things, increases the total aggregate commitment to ​ As of March 31, 2021, the two facilities under the Credit Agreement included: ​ ● 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 $770.0 million; and ​ ● a $400.0 million revolving credit facility to be used for general corporate purposes. ​ 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. 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. ​ The average interest rates for the Credit Agreement were 2.7% and 3.5% for the three months ended March 31, 2021 and 2020, respectively. ​ 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 throughout the next twelve months 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 March 31, 2021 the Partnership estimated working capital revolving credit facility borrowings will equal or exceed 31, 2021, 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 31, 2020, respectively. The increase in total borrowings under the working capital revolving credit facility of 31, 2020 was in part due to higher prices. ​ As of March 31, 2021, the Partnership had total borrowings outstanding under the Credit Agreement of $385.8 million, including $33.4 million outstanding on the revolving credit facility. In addition, the Partnership had outstanding letters of credit of million. Subject to borrowing base limitations, the total remaining availability for borrowings and letters of credit was ​ 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 March 31, 2021. 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). ​ Please read Note 8 of Notes to Consolidated Financial Statements in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information on the Credit 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. The Partnership had unamortized deferred financing fees of 31, 2020, respectively. ​ Unamortized fees related to the Credit Agreement are included in other current assets and other long-term assets and amounted to $3.9 million and $4.8 million at March 31, 2021 and December 31, 2020, 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 31, 2020, respectively. Unamortized fees related to the Sale-Leaseback Transaction (defined below) are presented as a direct deduction from the carrying amount of the financing obligation and amounted to ​ Amortization expense of approximately $1.3 million for each of the three months ended March 31, 2021 and 2020, 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 periods presented (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ ​ March 31, ​ ​ ​ 2021 2020 Borrowings from working capital revolving credit facility ​ $ 533,500 ​ $ 417,500 ​ Payments on working capital revolving credit facility ​ ​ (365,500) ​ ​ (532,500) ​ Net borrowings from (payments on) working capital revolving credit facility ​ $ 168,000 ​ $ (115,000) ​ Net (payments on) borrowings from revolving credit facility ​ $ (88,600) ​ $ 50,000 ​ ​ Fifth Amendment to the Credit Agreement ​ On May 5, 2021, the Partnership and certain of its subsidiaries entered into the Fifth Amendment to Third Amended and Restated Credit Agreement (the “Fifth Amendment”), which further amends the Credit Agreement. Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Credit Agreement. ​ The Fifth Amendment amends certain terms, provisions and covenants of the Credit Agreement, including, without limitation: (i) increases the aggregate commitments under the facilities with the commitment under the working capital revolving credit facility increased to $800.0 million from $770.0 million and the commitment under the revolving credit facility increased to $450.0 million from $400.0 million; ​ (ii) extends the maturity date for the Credit Agreement from April 29, 2022 to May 6, 2024; ​ (iii) decreases by 0.125% the applicable rate under the working capital 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; and ​ (iv) reduces the Eurocurrency rate floor to zero basis points and the cost of funds rate floor to zero basis points. ​ All other material terms of the Credit Agreement remain substantially the same as disclosed in Note 8 of Notes to Consolidated Financial Statements in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2020. ​ Senior Notes ​ The Partnership had 7.00% senior notes due 2027 and 6.875% senior notes due 2029 outstanding at March 31, 2021 and December 31, 2020.

Derivative Financial Instruments
Derivative Financial Instruments	Note 8. 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. The Partnership uses these exchange-traded and OTC derivatives to hedge commodity price risk associated with its inventory, fuel purchases 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. ​ The following table summarizes the notional values related to the Partnership’s derivative instruments outstanding at March 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ Units (1) Unit of Measure Exchange-Traded Derivatives ​ ​ ​ ​ ​ Long ​ 117,583 Thousands of barrels ​ Short ​ (122,821) Thousands of barrels ​ ​ ​ ​ ​ ​ ​ OTC Derivatives (Petroleum/Ethanol) ​ ​ ​ ​ ​ Long ​ 12,948 Thousands of barrels ​ Short ​ (6,281) 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 ​ The Partnership utilizes fair value hedges and cash flow hedges to hedge commodity price risk. ​ Fair Value Hedges ​ 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. ​ 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 statements 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 periods presented (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Statement of Gain (Loss) ​ Three Months Ended ​ ​ Recognized in Income on ​ March 31, ​ ​ Derivatives ​ 2021 ​ 2020 Derivatives in fair value hedging relationship ​ ​ ​ ​ Exchange-traded futures contracts and OTC derivative contracts for petroleum commodity products Cost of sales ​ $ (5,494) ​ $ 48,335 ​ Hedged items in fair value hedge relationship ​ ​ ​ ​ ​ ​ ​ ​ ​ Physical inventory Cost of sales ​ $ 3,500 ​ $ (50,182) ​ ​ Cash Flow Hedges ​ The Partnership’s sales and cost of sales fluctuate with changes in commodity prices. In addition to the Partnership’s commodity price risk associated with its inventory and undelivered forward commodity purchases and sales, the Partnership’s gross profit may fluctuate in periods where commodity prices are rising or declining depending on the magnitude and duration of the commodity price change. In the Partnership’s GDSO segment, the Partnership has observed trends where margins may improve in periods where wholesale gasoline prices are declining and margins may compress during periods where wholesale gasoline prices are rising. To hedge the Partnership’s cash flow risk as a result of this observed trend in the GDSO segment, the Partnership has entered into exchange-traded commodity swap contracts and has designated them as a cash flow hedge of its fuel purchases designed to reduce its cost of fuel if market prices rise through 2021 or increase its cost of fuel if market prices decrease through 2021. For a derivative instrument being designated as a cash flow hedge, the effective portion of the derivative gain or loss is initially reported as a component of other comprehensive income (loss) and subsequently reclassified into the consolidated statement of income through cost of goods sold in the same period that the hedged exposure affects earnings. ​ During the second quarter ended June 30, 2020, to hedge the Partnership’s cash flow risk relative to certain trends and the fluctuations in commodity prices observed within the GDSO segment, the Partnership entered into exchange-traded commodity swap contracts and designated them as a cash flow hedge of its fuel purchases designed to reduce its cost of fuel if market prices rise through 2021 or increase its cost of fuel if market prices decrease through 2021. 31, 2021 and 2020, respectively. The amount of income reclassified from other comprehensive income into cost of sales for derivatives designated in cash flow hedging relationships was 31, 2021 and 2020, respectively. The amount of income recognized in other comprehensive income as of March 31, 2021 and expected to be reclassified into earnings within the next nine months was ​ Derivatives Not Accounted for as Hedges ​ The Partnership utilizes petroleum and ethanol commodity contracts 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 statements 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 barrels of commodity products at any one point in time. Changes in fair value of these derivative instruments are recognized in the consolidated statements of operations through cost of sales. ​ 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 periods presented (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Statement of Gain (Loss) ​ Three Months Ended ​ Derivatives not designated as ​ Recognized in ​ March 31, ​ hedging instruments Income on Derivatives 2021 ​ 2020 Commodity contracts Cost of sales ​ $ 4,908 ​ $ (450) ​ ​ 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. ​ 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 March 31, 2021 and December 31, 2020 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 ​ ​ ​ ​ Derivatives ​ Derivatives Not ​ ​ ​ ​ ​ ​ ​ Designated as ​ Designated as ​ ​ ​ ​ ​ ​ ​ Hedging ​ Hedging ​ ​ ​ ​ ​ Balance Sheet Location ​ Instruments ​ Instruments ​ Total Asset Derivatives: ​ ​ ​ ​ Exchange-traded derivative contracts Broker margin deposits ​ $ 10,270 ​ $ 91,888 ​ $ 102,158 ​ Forward derivative contracts (1) Derivative assets ​ ​ — ​ ​ 8,584 ​ ​ 8,584 ​ Total asset derivatives ​ ​ ​ $ 10,270 ​ $ 100,472 ​ $ 110,742 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liability Derivatives: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Exchange-traded derivative contracts Broker margin deposits ​ $ — ​ $ (210,203) ​ $ (210,203) ​ Forward derivative contracts (1) ​ Derivative liabilities ​ ​ — ​ ​ (21,001) ​ ​ (21,001) ​ Total liability derivatives ​ ​ ​ $ — ​ $ (231,204) ​ $ (231,204) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ ​ ​ Derivatives ​ Derivatives Not ​ ​ ​ ​ ​ ​ ​ Designated as ​ Designated as ​ ​ ​ ​ ​ ​ ​ Hedging ​ Hedging ​ ​ ​ ​ ​ Balance Sheet Location ​ Instruments ​ Instruments ​ Total Asset Derivatives: ​ ​ ​ ​ Exchange-traded derivative contracts Broker margin deposits ​ $ 7,628 ​ $ 72,424 ​ $ 80,052 ​ Forward derivative contracts (1) Derivative assets ​ ​ — ​ ​ 16,556 ​ ​ 16,556 ​ Total asset derivatives ​ ​ ​ $ 7,628 ​ $ 88,980 ​ $ 96,608 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liability Derivatives: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Exchange-traded derivative contracts ​ Broker margin deposits ​ $ (7,183) ​ $ (93,874) ​ $ (101,057) ​ Forward derivative contracts (1) Derivative liabilities ​ ​ — ​ ​ (12,055) ​ ​ (12,055) ​ Total liability derivatives ​ ​ ​ $ (7,183) ​ $ (105,929) ​ $ (113,112) ​ (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 ​ 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 March 31, 2021 and December 31, 2020 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value at March 31, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash Collateral ​ ​ ​ ​ Level 1 Level 2 Level 3 Netting Total Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Forward derivative contracts (1) ​ $ — ​ $ 7,723 ​ $ 861 ​ $ — ​ $ 8,584 ​ Exchange-traded/cleared derivative instruments (2) ​ (108,045) ​ — ​ — ​ 139,393 ​ 31,348 ​ Pension plans ​ 19,657 ​ — ​ — ​ — ​ 19,657 ​ Total assets ​ $ (88,388) ​ $ 7,723 ​ $ 861 ​ $ 139,393 ​ $ 59,589 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Forward derivative contracts (1) ​ $ — ​ $ (20,505) ​ $ (496) ​ $ — ​ $ (21,001) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value at December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash Collateral ​ ​ ​ ​ Level 1 Level 2 Level 3 Netting Total Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Forward derivative contracts (1) ​ $ — ​ $ 16,124 ​ $ 432 ​ $ — ​ $ 16,556 ​ Exchange-traded/cleared derivative instruments (2) ​ (21,005) ​ — ​ — ​ 42,666 ​ 21,661 ​ Pension plans ​ 19,495 ​ — ​ — ​ — ​ 19,495 ​ Total assets ​ $ (1,510) ​ $ 16,124 ​ $ 432 ​ $ 42,666 ​ $ 57,712 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Forward derivative contracts (1) ​ $ — ​ $ (11,970) ​ $ (85) ​ $ — ​ $ (12,055) ​ (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 8. ​ 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 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 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 ​ December 31, 2020 ​ ​ Face ​ Fair ​ Face ​ Fair ​ ​ Value ​ Value ​ Value ​ Value ​ 7.00% senior notes due 2027 $ 400,000 ​ $ 422,000 ​ $ 400,000 ​ $ 427,000 ​ 6.875% senior notes due 2029 $ 350,000 ​ $ 373,625 ​ $ 350,000 ​ $ 378,000 ​ ​ 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 estimated range and weighted average for these inputs include the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 ​ December 31, 2020 ​ ​ ​ Low ​ High ​ Weighted ​ Low ​ High ​ Weighted ​ Product ($ per barrel) ​ ($ per barrel) ​ Average ​ ($ per barrel) ​ ($ per barrel) ​ Average Crude oil ​ $ (4.25) ​ $ 0.25 ​ $ (2.04) ​ $ (4.25) ​ $ (3.15) ​ $ (3.61) ​ ​ The respective weighted averages were calculated by weighting the contractual volumes of the location basis, transportation and throughput costs net of an estimated margin for current market participants. Gains and losses recognized in earnings (or changes in net assets) are disclosed in Note 8. ​ Uncertainty in changes in the significant unobservable inputs to the fair value measurement if those inputs reasonably could have been different at the reporting date is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Significant ​ ​ ​ ​ ​ Impact on Fair Value ​ Unobservable Input Position Change to Input Measurement ​ Location basis ​ Long ​ Increase ​ Gain (loss) ​ Location basis ​ Short ​ Increase ​ Loss (gain) ​ Transportation ​ Long ​ Increase ​ Gain (loss) ​ Transportation ​ Short ​ Increase ​ Loss (gain) ​ Throughput costs ​ Long ​ Increase ​ Gain (loss) ​ Throughput costs ​ Short ​ Increase ​ Loss ​ ​ 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 period, accounting guidance requires quantitative disclosures about the fair value measurements separately for each major category.

Environmental Liabilities and Renewable Identification Numbers (RINs)	Note 10. Environmental Liabilities and Renewable Identification Numbers ​ Environmental Liabilities ​ The following table presents a summary roll forward of the Partnership’s environmental liabilities at March 31, 2021 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance at ​ ​ ​ ​ ​ Other Balance at ​ ​ December 31, ​ Payments ​ Dispositions ​ Adjustments ​ March 31, Environmental Liability Related to: ​ 2020 ​ 2021 ​ 2021 ​ 2021 ​ 2021 Retail gasoline stations ​ $ 49,980 ​ $ (570) ​ $ (139) ​ $ 27 ​ $ 49,298 ​ Terminals ​ 3,641 ​ (16) ​ — ​ — ​ 3,625 ​ Total environmental liabilities ​ $ 53,621 ​ $ (586) ​ $ (139) ​ $ 27 ​ $ 52,923 ​ Current portion ​ $ 4,455 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 4,455 ​ Long-term portion ​ 49,166 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 48,468 ​ Total environmental liabilities ​ $ 53,621 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 52,923 ​ ​ 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 ​ The Partnership may enter into RIN forward purchase and sales commitments. Total losses from firm non-cancellable commitments were immaterial at both March 31, 2021 and December 31, 2020.

(“GPC”), an affiliate of the Partnership that was 100% owned by members of the Slifka family, pursuant to which the Partnership provided GPC with certain tax, accounting, treasury, legal, information technology, human resources and financial operations support services for which GPC paid the Partnership a monthly services fee at an agreed amount subject to approval by the Conflicts Committee of the board of directors of the General Partner. In connection with GPC’s entry into a plan of liquidation and dissolution, the Second Amended and Restated Services Agreement was terminated by mutual agreement of the parties effective December 31, 2020. Effective January 1, 2021, the Partnership entered into a new services agreement with various entities which own limited partner and/or general partner interests in the Partnership and which are 100% owned by members of the Slifka family (the “Slifka Entities Services Agreement”), pursuant to which the Partnership provides certain tax, accounting, treasury, and legal support services for which such Slifka entities pay the Partnership an annual services fee of $20,000 , and which Slifka Entities Services Agreement has been approved by the Conflicts Committee of the board of directors of the General Partner. The Slifka Entities Services Agreement is for an indefinite term and any party may terminate some or all of the services upon ninety (90) days’ advance written notice. As of March 31, 2021, no such notice of termination had been given by any party to the Slifka Entities Services Agreement. ​ 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 31, 2021 and 2020, respectively. The Partnership also reimburses the General Partner for its contributions under the General Partner’s 401(k) Savings and Profit Sharing Plans and the General Partner’s qualified and non-qualified pension plans. ​ The table below presents receivables from GPC and the General Partner (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ ​ 2021 2020 Receivables from GPC ​ $ 3 ​ $ 28 ​ Receivables from the General Partner (1) ​ ​ 4,517 ​ ​ 2,382 ​ Total ​ $ 4,520 ​ $ 2,410 ​ (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.

Long-Term Incentive Plan	Note 12. Long-Term Incentive Plan ​ 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. Please read Note 17 of Notes to Consolidated Financial Statements in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information on the LTIP. ​ 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 phantom units at December 31, 2020 402,570 ​ 9.47 ​ Vested (3,796) ​ 26.38 ​ Outstanding non—vested phantom units at March 31, 2021 398,774 ​ 9.31 ​ ​ The Partnership recorded total compensation expense related to the outstanding LTIP awards of $0.3 million for each of the three months ended March 31, 2021 and 2020, 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 March 31, 2021 was approximately $1.3 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 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 ​ 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 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 distribution to common unitholders during 2021 (in thousands, except per unit data): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Per Unit ​ ​ ​ ​ ​ ​ ​ ​ Cash Distribution ​ Quarter ​ Cash ​ Common ​ General ​ Incentive ​ Total Cash Payment Date Ended ​ Distribution ​ Units ​ Partner ​ Distribution ​ Distribution 2/12/2021 (1) ​ 12/31/20 ​ $ 0.550 ​ $ 18,698 ​ $ 130 ​ $ 512 ​ $ 19,340 ​ (1) This distribution resulted in the Partnership reaching its third target level distribution for this quarter. As a result, the General Partner, as the holder of the IDRs, received an incentive distribution. In addition, on April 26, 2021, the board of directors of the General Partner declared a quarterly cash distribution of $0.5750 per unit ($2.30 per unit on an annualized basis) on all of its outstanding common units for the period from January 1, 2021 through March 31, 2021. On May 14, 2021, the Partnership will pay this cash distribution to its common unitholders of record as of the close of business on May 10, 2021. ​ Series A Preferred Units ​ Distributions on the Series A Preferred Units are cumulative from August 7, 2018, the original issue date of the Series A Preferred Units, 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 “Series 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 Series A 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 Series A Distribution Payment Date. ​ The Partnership paid the following cash distribution on the Series A Preferred Units during 2021 (in thousands, except per unit data): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Per Unit ​ ​ Cash Distribution ​ Quarterly Period ​ Cash ​ Total Cash Payment Date Covering Distribution Distribution 2/16/2021 ​ 11/15/20 - 2/14/21 ​ $ 0.609375 ​ $ 1,682 ​ ​ In addition, on April 19, 2021, 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 February 15, 2021 through May 14, 2021. This distribution will be payable on May ​ Series B Preferred Units ​ The Series B Preferred Units are a new class of equity security that rank (a) senior to common units representing limited partner interests in the Partnership, incentive distributions rights and each other class or series of the Partnership’s limited partner interests and other equity securities in the Partnership established after March 24, 2021, the original issue date of the Series B Preferred Units (the “Series B Original Issue Date”), that is not expressly made senior to or on parity with the Series A Preferred Units and the Series B Preferred Units as to the payment of distributions and amounts payable upon a liquidation, and (b) on parity with respect to distributions or amounts payable upon a liquidation event, as applicable, with the Series A Preferred Units and the Series B Preferred Units and each other and any class of series of limited partner interests or other equity securities of the Partnership established after the Series B Original Issue Date with terms expressly providing that such class or series ranks on parity with the Series A Preferred Units and the Series B Preferred Unit with respect to distribution rights and rights upon liquidation. ​ Distributions on the Series B Preferred Units are cumulative from the Series B Original Issue Date and payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year (each, a “Series B Distribution Payment Date”), commencing on May 15, 2021, 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. ​ On April 19, 2021, the board of directors of the General Partner declared the initial quarterly cash distribution of $0.3365 per unit on the Series B Preferred Units, covering the period from March 24, 2021 (the issuance date of the Series B Preferred Units) through May 14, 2021. This distribution will ​ The distribution rate for the Series B Preferred Units is 9.50% per annum of the $25.00 liquidation preference per Series B Preferred Unit (equal to $2.375 per Series B Preferred Unit per annum). ​ At any time on or after May 15, 2026, the Partnership may redeem, in whole or in part, the Series B Preferred Units at a redemption price in cash of $25.00 per Series B Preferred Unit plus an amount equal to all accumulated and unpaid distributions thereon to, but excluding, the date of redemption, whether or not declared. The Partnership must provide not less than 30 days ’ and not more than 60 days ’ advance written notice of any such redemption. ​ Upon the occurrence of a Series B Change of Control (as defined in the partnership agreement), the Partnership may, at its option, redeem the Series B Preferred Units, in whole or in part, within 120 days after the first date on which such Series B Change of Control occurred, by paying $25.00 per Series B Preferred Unit, plus all accumulated and unpaid distributions to, but excluding, the date of redemption, whether or not declared. If, prior to the Series B Change of Control Conversion Date (as defined in the partnership agreement), the Partnership exercises its redemption rights relating to Series B Preferred Units, holders of the Series B Preferred Units that the Partnership has elected to redeem will not have the conversion right discussed below related to a Series B Change of Control. ​ Upon the occurrence of a Series B Change of Control, each holder of Series B Preferred Units will have the right (unless, prior to the Series B Change of Control Conversion Date, the Partnership provides notice of its election to redeem the Series B Preferred Units) to convert some or all of the Series B Preferred Units held by such holder on the Series B Change of Control Conversion Date into a number of common units per Series B Preferred Unit to be converted equal to the lesser of (a) the quotient obtained by dividing (i) the sum of the $25.00 liquidation preference plus the amount of any accumulated and unpaid distributions to, but excluding, the Series B Change of Control Conversion Date (unless the Series B Change of Control Conversion Date is after a record date for a Series B Preferred Unit distribution payment and prior to the corresponding Distribution Payment Date, in which case no additional amount for such accumulated and unpaid distribution will be included in this sum) by (ii) the Common Unit Price (as defined in the partnership agreement) and (b) 2.1533, subject, in each case, to certain exceptions and adjustments. ​ Any such redemptions would be effected only out of funds legally available for such purposes and would be subject to compliance with the provisions of the Partnership’s outstanding indebtedness. ​ Holders of Series B Preferred Units generally have no voting rights, except for limited voting rights with respect to (i) potential amendments to the partnership agreement that would have a material adverse effect on the terms of the Series B Preferred Units, (ii) the creation or issuance of any Preferred Unit Parity Securities (as defined in the partnership agreement) (including any additional Series A Preferred Units and Series B Preferred Units) if the cumulative distributions payable on then outstanding Series B Preferred Units (or Preferred Unit Parity Securities, including the Series A Preferred Units, if applicable) are in arrears, (iii) the creation or issuance of any Preferred Unit Senior Securities (as defined in the partnership agreement) and (iv) the declaration or payment of any distribution to the holders of common units out of capital surplus.

Income Taxes
Income Taxes	Note 15. 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. ​ 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 an immaterial amount for the three months ended March 31, 2021. ​ The Partnership computed its tax provision for the three months ended March 31, 2021 based upon the year-to-date effective tax rate as opposed to an estimated annual effective tax rate. Given a reliable estimate of the annual effective tax rate cannot be made, the Partnership concluded that the year-to-date effective tax rate is the most appropriate method to use for the three months ended March 31, 2021. ​ Unrecognized tax benefits represent uncertain tax positions for which reserves have been established. The Partnership had gross-tax effected unrecognized tax benefits of 31, 2020. ​ GMG files income tax returns in the United States and various state jurisdictions. As of March 31, 2021, with few exceptions, the Partnership was subject to income tax examination by tax authorities for all years dated back to 2017. ​ On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) was enacted and signed into law. The CARES Act is an emergency economic stimulus package that includes spending and tax breaks to strengthen the United States economy and fund a nationwide effort to curtail the effect of COVID-19. The CARES Act provides certain tax changes in response to the COVID-19 pandemic, including the temporary removal of certain limitations on the utilization of net operating losses, permitting the carryback of net operating losses generated in 2018, 2019 or 2020 to the five preceding taxable years, increasing the ability to deduct interest expense, deferring the employer share of social security tax payments, as well as amending certain provisions of the previously enacted Tax Cuts and Jobs Act. As a result, the Partnership recognized a benefit of months ended March 31, 2020. On January 15, 2021, the Partnership received cash refunds totaling million associated with the carryback of losses generated in 2018 with respect to the 2016 and 2017 tax years. This income tax receivable is included in prepaid expenses and other current assets in the accompanying consolidated balance sheet as of December 31, 2020.

Legal Proceedings
Legal Proceedings	Note 17. 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 10 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 ​ In October 2020, the Partnership was served with a complaint filed against the Partnership and its wholly owned subsidiary, Global Companies LLC (“Global Companies”) alleging, among other things, wrongful death and loss of consortium. The complaint, filed in the Middlesex County Superior Court of the Commonwealth of Massachusetts, alleges, among other things, that a truck driver (whose estate is a co-plaintiff), while loading gasoline and diesel fuel at terminals owned and operated by the Partnership located in Albany, New York and Burlington, Vermont, was exposed to benzene-containing products and/or vapors therefrom. The Partnership and Global Companies have meritorious defenses to the allegations in the complaint and will vigorously contest the actions taken by the plaintiffs. ​ On June 1, 2020, Basin Transload filed for reorganization in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”) under Chapter 11 of the United States Bankruptcy Code. Pursuant to the terms of a settlement agreement entered into as of August 12, 2020 by and among the Partnership, Global Operating LLC (“Global Operating”), Basin Transload and the minority members of Basin Transload (the “Basin Settlement Agreement”), Basin Transload filed a motion with the Bankruptcy Court to voluntarily dismiss the bankruptcy petition. On September 14, 2020, the Bankruptcy Court issued an order approving the Basin Settlement Agreement and dismissing the bankruptcy petition. The order became final and non-appealable on September 28, 2020. In connection with the Basin Settlement Agreement, Global Operating acquired the minority members’ collective ​ 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 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 Partnership denied the allegations and the NYSDEC did not issue any such NOV. The Albany Terminal is a -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 authorized 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 if there are violations of the New York SIP seeking compliance and penalties. The Partnership has denied the NOV allegations and asserts that the permits issued by the NYSDEC comply with the CAA and applicable state air permitting requirements and that no material violation of law 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 signed the tolling agreements with respect to this matter, as requested by the EPA, and such agreements currently extend through June 30, 2021. 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. Additionally, the Partnership has submitted a Title V Permit renewal and a request for modifications to its existing Title V Permit. The Partnership believes that it has meritorious defenses against all allegations. ​ 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 25, 2019. The Consent Decree was entered by the Court on December 19, 2019. The Partnership believes that compliance with the Consent Decree and implementation of the requirements of the Consent Decree will have no material impact on its operations. ​

The Partnership adopted this standard on January 1, 2021 with no material impact on the Partnership’s consolidated financial statements.

Upon consolidation, all intercompany balances and transactions have been eliminated. ​ The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial condition and operating results for the interim periods.

In connection with the terms of an agreement between the Partnership and the minority members of Basin Transload on September 29, 2020, the Partnership acquired the minority members’ collective ​ 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 financial statements for the three months ended March 31, 2020.
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. The uncertainty surrounding the short and long-term impact of COVID-19, including the inability to project the timing of an economic recovery, may have an impact on the Partnership’s use of estimates. 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 credit losses, (v) assumptions used to evaluate goodwill, property and equipment and intangibles for impairment, (vi) environmental and asset retirement obligation provisions, and (vii) weighted average discount rate used in lease accounting. Although the Partnership believes its estimates are reasonable, actual results could differ from these estimates.
Concentration of Risk	Concentration of Risk ​ 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. However, the COVID-19 pandemic has had a negative impact on gasoline demand and the extent and duration of that impact remains uncertain. 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 periods presented: ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ ​ March 31, ​ ​ 2021 2020 Gasoline sales: gasoline and gasoline blendstocks (such as ethanol) 62 % 67 % Distillates (home heating oil, diesel and kerosene) and residual oil sales 33 % 29 % Crude oil sales and crude oil logistics revenue 1 % — % Convenience store sales, rental income and sundries ​ 4 % 4 % Total 100 % 100 % ​ The following table presents the Partnership’s product margin by segment as a percentage of the consolidated product margin for the periods presented: ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ ​ March 31, ​ ​ 2021 2020 Wholesale segment 18 % 3 % Gasoline Distribution and Station Operations segment 79 % 93 % Commercial segment ​ 3 % 4 % Total 100 % 100 % ​ See Note 14, “Segment Reporting,” for additional information on the Partnership’s operating segments. ​ None of the Partnership’s customers accounted for greater than 10% of total sales for the three months ended March 31, 2021 and 2020.
