Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Description of Business Enviva Partners, LP (together with its subsidiaries, “we,” “us,” “our,” or the “Partnership”) supplies utility-grade wood pellets primarily to major power generators under long-term, take-or-pay off-take contracts. We procure wood fiber and process it into utility-grade wood pellets and load the finished wood pellets into railcars, trucks and barges for transportation to deep-water marine terminals, where they are received, stored and ultimately loaded onto oceangoing vessels for delivery under long-term, take-or-pay off-take contracts to our customers in the United Kingdom (the “U.K.”), Europe and increasingly Japan. We own and operate nine industrial-scale wood pellet production plants located in the Southeast United States. In addition to the volumes from our plants, we also procure wood pellets from third parties. Wood pellets are exported from our wholly owned deep-water marine terminals at the Port of Chesapeake, Virginia and terminal assets at the Port of Wilmington, North Carolina (the “Wilmington terminal”) and from third-party deep-water marine terminals in Mobile, Alabama, Panama City, Florida and Savannah, Georgia under a short-term contract, a long-term contract and a lease and associated terminal services agreement, respectively. Basis of Presentation The unaudited financial statements and notes have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments and accruals necessary for a fair presentation have been included. All such adjustments and accruals are of a normal and recurring nature unless disclosed otherwise. All intercompany balances and transactions have been eliminated in consolidation. The results reported in the financial statements are not necessarily indicative of the results that may be reported for the entire year. The unaudited financial statements and notes should be read in conjunction with the audited financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2020. Enviva Pellets Greenwood On July 1, 2020, we acquired from our sponsor all of the limited liability company interests in Enviva Pellets Greenwood Holdings II, LLC, the indirect owner of Enviva Pellets Greenwood, LLC (“Greenwood”), which owns a wood pellet production plant located in Greenwood, South Carolina (the “Greenwood plant” and such transaction, the “Greenwood Drop-Down”). The Greenwood Drop-Down was an asset acquisition between entities under common control and accounted for on the carryover basis of accounting. Accordingly, we recorded net assets of $67.8 million as of July 31, 2020 to reflect the Greenwood Drop-Down. Georgia Biomass Holding LLC On July 31, 2020, Enviva Pellets Waycross Holdings, LLC, a wholly owned subsidiary of the Partnership, acquired all of the limited liability company interests in Georgia Biomass Holding LLC, a Georgia limited liability company (“Georgia Biomass” and such transaction, the “Georgia Biomass Acquisition”) and the indirect owner of a wood pellet production plant located in Waycross, Georgia (the “Waycross plant”). In August 2020, Georgia Biomass converted to a limited liability company organized under the laws of the State of Delaware under the name Enviva Pellets Waycross Holdings Sub, LLC. The Georgia Biomass Acquisition was recorded as a business combination and accounted for using the acquisition method. Assets acquired and liabilities assumed were recognized at fair value on the acquisition date of July 31, 2020, and the difference between the consideration transferred, excluding acquisition-related costs, and the fair values of the assets acquired and liabilities assumed was recognized as goodwill. Accordingly, we recorded net identifiable assets acquired and liabilities assumed of $150.0 million and goodwill of $14.0 million as of July 31, 2020 to reflect the Georgia Biomass Acquisition. Enviva Wilmington Holdings, LLC On April 2, 2019, we acquired (the “Hamlet Drop-Down”) from our sponsor all of the issued and outstanding Class B Units in Enviva Wilmington Holdings, LLC (the “Hamlet JV”), a limited liability company owned by our sponsor and John Hancock Life Insurance Company (U.S.A.) and certain of its affiliates (collectively, as applicable, “John Hancock”). On the date of acquisition, we began to consolidate the Hamlet JV as a variable interest entity of which we are the primary beneficiary. As managing member, we have the sole power to direct the activities that most impact the economics of the Hamlet JV. Additionally, as the Class B Units represent a controlling interest in the Hamlet JV, we account for the Hamlet JV as a consolidated subsidiary, not as a joint venture. The Hamlet Drop-Down was an asset acquisition between entities under common control and accounted for on the carryover basis of accounting. Accordingly, the consolidated financial statements for the period beginning April 2019 reflect the acquisition.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies During interim periods, we follow the accounting policies disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Recently Adopted Accounting Standards On January 1, 2021, we adopted ASU 2019-12- Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which removes certain exceptions for recognizing deferred taxes for investments, performing intraperiod allocation and calculating income taxes in interim periods. The ASU also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. The adoption did not have a material impact on the financial statements. Recently Issued Accounting Standards not yet Adopted Currently, there are no recently issued accounting standards not yet adopted by us that we expect to be reasonably likely to materially impact our financial position, results of operations or cash flows.

Revenue

Revenue	3 Months Ended
Revenue	Mar. 31, 2021
Revenue from Contract with Customer [Abstract]
Revenue	Revenue We disaggregate our revenue into two categories: product sales and other revenue. Product sales includes sales of wood pellets. Other revenue includes fees associated with customer requests to cancel, defer or accelerate shipments in satisfaction of the related performance obligation and third- and related-party terminal services fees. Other revenue also includes fees received for other services, including for sales and marketing, scheduling, sustainability, consultation, shipping and risk management services, where the revenue is recognized when we have satisfied the performance obligation and have a right to the corresponding fee. These categories best reflect the nature, amount, timing and uncertainty of our revenue and cash flows. Performance Obligations As of March 31, 2021, the aggregate amount of consideration from contracts with customers allocated to the performance obligations that were unsatisfied or partially satisfied was approximately $14.1 billion. This amount excludes forward prices related to variable consideration including inflation, foreign currency and commodity prices. Also, this amount excludes the effects of the related foreign currency derivative contracts as they do not represent contracts with customers. As of April 1, 2021, we expect to recognize approximately 5.0% of our remaining performance obligations as revenue during the remainder of 2021, an additional 9.0% in 2022 and the balance thereafter. Our off-take contracts expire at various times through 2043 and our terminal services contract expires in 2021. Variable Consideration Variable consideration from off-take contracts arises from several pricing features in our off-take contracts, pursuant to which such contract pricing may be adjusted in respect of particular shipments to reflect differences between certain contractual quality specifications of the wood pellets as measured both when the wood pellets are loaded onto ships and unloaded at the discharge port as well as certain other contractual adjustments. Variable consideration from our terminal services contract arises from price increases based on agreed inflation indices and from above-minimum throughput quantities or services. There was no variable consideration from our terminal services contract for the three months ended March 31, 2021 and 2020. For the three months ended March 31, 2021 and 2020, we recognized $0.4 million and $0.2 million, respectively, of product sales revenue related to performance obligations satisfied in previous periods. Contract Balances Accounts receivable related to product sales as of March 31, 2021 and December 31, 2020 were $77.1 million and $108.5 million, respectively. Of these amounts, $59.2 million and $95.0 million, as of March 31, 2021 and December 31, 2020, respectively, related to amounts that were not yet billable under our contracts with customers pending finalization of prerequisite billing documentation. The amounts that had not been billed are billed upon receipt of prerequisite billing documentation, where substantially all is typically billed one to two weeks after full loading of the vessel and where the remaining balance is typically billed one to two weeks after discharge of the vessel. As of March 31, 2021 and December 31, 2020, we had $0.1 million and $4.9 million, respectively of deferred revenue for future performance obligations under contracts associated with off-take contracts. Other Accrued and other current liabilities included approximately $23.4 million and $50.6 million at March 31, 2021 and December 31, 2020, respectively, for amounts associated with our product sales.

Risks and Uncertainties [Abstract]
Significant Risks and Uncertainties, Including Business and Credit Concentrations	Significant Risks and Uncertainties, Including Business and Credit Concentrations Our business is significantly impacted by greenhouse gas emission and renewable energy legislation and regulations in the U.K., European Union (“EU”) as well as its member states and Japan. If the U.K., the EU or its member states or Japan significantly modify such legislation or regulations, then our ability to enter into new contracts as our existing contracts expire may be materially affected. Our current product sales are primarily to industrial customers located in the U.K., Denmark, Belgium and the Netherlands. Product sales to third-party customers that accounted for 10% or a greater share of consolidated product sales were as follows: Three Months Ended March 31, 2021 2020 Customer A 29% 35% Customer C 16% 24% Customer D 19% 15% Customer E 16% 6%

Derivative Instruments

Derivative Instruments	3 Months Ended
Derivative Instruments	Mar. 31, 2021
Derivative Instrument Detail [Abstract]
Derivative Instruments	Derivative Instruments We use derivative instruments to partially offset our business exposure to foreign currency exchange and interest rate risk. We may enter into foreign currency forward and option contracts to offset some of the foreign currency exchange risk on expected future cash flows and interest rate swaps to offset some of the interest rate risk on expected future cash flows on certain borrowings. The preponderance of our off-take contracts are U.S. Dollar-denominated. We are primarily exposed to fluctuations in foreign currency exchange rates related to a minority of our off-take contracts that require future deliveries of wood pellets to be settled in British Pound Sterling (“GBP”) and Euro (“EUR”). Our derivative instruments expose us to credit risk to the extent that hedge counterparties may be unable to meet the terms of the applicable derivative instrument. We seek to mitigate such risks by limiting our counterparties to major financial institutions. In addition, we monitor the potential risk of loss with any one counterparty resulting from credit risk. Management does not expect material losses as a result of defaults by counterparties. We use derivative instruments to manage cash flow and do not enter into derivative instruments for speculative or trading purposes. We have entered and may continue to enter into foreign currency forward contracts, purchased option contracts or other instruments to partially manage this risk. In 2020, we entered into pay-fixed, receive-variable interest rate swaps that expire in September 2021 and October 2021 to hedge interest rate risk associated with our variable rate borrowings under our senior secured revolving credit facility that are not designated and accounted for as cash flow hedges. Derivative instruments are classified as Level 2 assets or liabilities based on inputs such as spot and forward benchmark interest rates (such as LIBOR) and foreign exchange rates. The fair value of derivative instruments at March 31, 2021 and December 31, 2020 were as follows: Asset (Liability) Balance Sheet Classification March 31, 2021 December 31, 2020 Not designated as hedging instruments: Interest rate swaps Accrued and other current liabilities $ (84) $ (119) Foreign currency exchange contracts: Prepaid and other current assets $ 545 $ 308 Other long-term assets 665 924 Accrued and other current liabilities (3,302) (2,224) Other long-term liabilities (3,568) (3,508) Total derivatives not designated as hedging instruments $ (5,744) $ (4,619) Unrealized losses related to the change in fair market value of interest rate swaps are recorded in interest expense and were $0.1 million and insignificant, respectively, for the three months ended March 31, 2021 and 2020. During the three months ended March 31, 2021 and 2020, product sales included net unrealized losses of $1.2 million and net unrealized gains of $6.8 million, respectively, related to the change in fair market value of foreign currency derivatives. Included in product sales on the condensed consolidated statements of operations are realized losses related to foreign currency derivatives settled of $1.0 million during the three months ended March 31, 2021 and realized gains of $0.2 million during the three months ended March 31, 2020. We enter into master netting arrangements designed to permit net settlement of derivative transactions among the respective counterparties. If we had settled all transactions with our respective counterparties at March 31, 2021, we would have had to pay a net settlement termination payment of $5.9 million, which differs by $0.2 million from the recorded fair value of the derivatives. We present our derivative assets and liabilities at their gross fair values. The notional amounts of outstanding derivative instruments associated with outstanding or unsettled derivative instruments as of March 31, 2021 and December 31, 2020 were as follows: March 31, 2021 December 31, 2020 Foreign exchange forward contracts in GBP £ 178,839 £ 143,565 Foreign exchange purchased option contracts in GBP £ 30,621 £ 51,601 Foreign exchange forward contracts in EUR € 24,503 € 12,968 Interest rate swaps $ 70,000 $ 70,000

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The amounts reported in the condensed consolidated balance sheets as cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, related-party receivables, net, accounts payable, related-party payables, net, and accrued and other current liabilities approximate fair value because of the short-term nature of these instruments. Derivative instruments and long-term debt including the current portion are classified as Level 2 instruments. Derivatives are classified as Level 2 as they are fair valued using inputs that are observable in active markets such as benchmark interest rates and foreign exchange rates (see Note 7, Derivative Instruments ). The fair value of our 2026 Notes was determined based on observable market prices in an active market and was categorized as Level 2 in the fair value hierarchy. The fair value of our Seller Note is classified as Level 2 and is estimated on discounted cash flow analyses based on observable inputs in active markets for debt with similar terms and remaining maturities. The carrying amount of other long-term debt, which is primarily composed of the senior secured revolving credit facility that resets based on a market rate, approximates fair value. The carrying amount and estimated fair value of long-term debt as of March 31, 2021 and December 31, 2020 was as follows: March 31, 2021 December 31, 2020 Carrying Fair Carrying Fair 2026 Notes $ 747,004 $ 788,437 $ 746,875 $ 796,875 Seller Note 35,421 37,376 37,571 40,405 Other long-term debt 168,000 168,000 122,000 122,000 Total long-term debt $ 950,425 $ 993,813 $ 906,446 $ 959,280

Enviva Management Company provides us with operations, general administrative, management and other services. The MSAs include rent and related amounts for noncancelable operating leases for office space in Maryland and North Carolina held by our sponsor. We believe the costs allocated to us have been made on a reasonable basis and are the best estimate of the costs that we would have incurred on a stand-alone basis. Enviva Partners reimburses Enviva Management Company for all direct or indirect internal or third-party expenses it incurs in connection with the provision of such services. Under the Hamlet JV’s MSA (the “Hamlet JV MSA”), the Hamlet JV pays an annual management fee to Enviva Management Company; to the extent allocated costs exceed the annual management fee, the additional costs are recorded with an increase to partners’ capital. In connection with the Hamlet Drop-Down, Enviva Management Company waived the Hamlet JV’s obligation to pay approximately $2.7 million of management fees payable to Enviva Management Company from the date thereof until July 1, 2020 (the “Hamlet JV MSA Fee Waiver”). Related-party amounts included on the unaudited condensed consolidated balance sheets under our MSAs were as follows: March 31, 2021 December 31, 2020 Finished goods inventory $ 3,301 $ 907 Related-party payables 8,419 8,650 Related-party amounts included on the unaudited condensed consolidated statements of operations under our MSAs were as follows: Three Months Ended March 31, 2021 2020 Cost of goods sold $ 24,301 $ 13,260 General and administrative expenses 8,770 7,689 During the three months ended March 31, 2021 and 2020, $0.7 million of fees expensed under the Hamlet JV MSA were waived and recorded as an increase to partners’ capital. Drop-Down Agreements Greenwood Drop-Down On the date of the Greenwood Drop-Down: • We entered into an agreement with our sponsor, pursuant to which our sponsor agreed to reimburse us for any construction costs incurred for the planned expansion of the Greenwood plant in excess of $28.0 million (the “Greenwood Make-Whole Agreement”). • We entered into an agreement with Enviva Management Company pursuant to which (1) Enviva Management Company waived our obligation to pay an aggregate of approximately $37.0 million in management services and other fees payable under our management services agreement with Enviva Management Company for the period from July 1, 2020 through the fourth quarter of 2021 and (2) Enviva Management Company will waive our obligation to pay certain management services and other fees during 2022 unless and until the Greenwood plant’s production volumes equal or exceed 50,000 metric tons (“MT”) in any calendar month, in each case, to provide cash flow support to us during the planned expansion of the Greenwood plant (the “Third EVA MSA Fee Waiver”). Pursuant to the Third EVA MSA Fee Waiver, during the three months ended March 31, 2021, $8.0 million was recorded as an increase to partners’ capital consisting of expenses waived under the agreement. Hamlet Drop-Down On the date of the Hamlet Drop-Down: • We entered into an agreement with our sponsor, pursuant to which (1) our sponsor agreed to guarantee certain cash flows from the Hamlet plant until June 30, 2020, (2) our sponsor agreed to reimburse us for construction cost overruns in excess of budgeted capital expenditures for the Hamlet plant, subject to certain exceptions, (3) we agreed to pay to our sponsor quarterly incentive payments for any wood pellets produced by the Hamlet plant in excess of forecast production levels through June 30, 2020 and (4) our sponsor agreed to retain liability for certain claims payable, if any, by the Hamlet JV (the “Hamlet Make-Whole Agreement”). • We entered into an agreement with Enviva Management Company to waive our obligation to pay an aggregate of approximately $13.0 million in fees payable under our MSA with Enviva Management Company (the “EVA MSA”) with respect to the period from the date of the Hamlet Drop-Down through the second quarter of 2020 (the “First EVA MSA Fee Waiver”). • The Hamlet JV entered into an interim services agreement (the “ISA”) with Enviva Hamlet Operator, LLC, a wholly owned subsidiary of our sponsor (“Hamlet Operator”), pursuant to which Hamlet Operator, as an independent contractor, agreed to manage, operate, maintain and repair the Hamlet plant and provide other services to the Hamlet JV for the period from July 1, 2019 through June 30, 2020 in exchange for a fixed fee per MT of wood pellets produced by the Hamlet plant during such period and delivered at place to the Wilmington terminal. Under and during the term of the ISA, Hamlet Operator agreed to (1) pay all operating and maintenance expenses at the Hamlet plant, (2) cover all reimbursable general and administrative expenses associated with the Hamlet plant and (3) pay other costs and expenses incurred by the Hamlet plant to produce and sell the wood pellets delivered to the Wilmington terminal from the Hamlet plant. Our sponsor guaranteed all obligations of Hamlet Operator under the ISA. The Hamlet Make-Whole Agreement, First EVA MSA Fee Waiver and ISA expired pursuant to their terms on June 30, 2020. For the three months ended March 31, 2020, $2.5 million of fees expensed under the Hamlet JV MSA and waived under the First EVA MSA Fee Waiver were recorded as an increase to partners’ capital. For the three months ended March 31, 2020, cost of goods sold included $10.6 million net of a cost of cover deficiency fee from our sponsor pursuant to the Hamlet Make-Whole Agreement as a result of Hamlet Operator’s failure to meet specified production levels, offset by the agreed-upon price due to Hamlet Operator for the wood pellets produced by the Hamlet plant that we sold. As of March 31, 2021 and December 31, 2020, related-party receivables included $0.4 million and $12.3 million related to the ISA. Greenwood Contract We were party to a contract with Greenwood to purchase wood pellets produced by the Greenwood plant through March 2022 (the “Greenwood Contract”). The Greenwood Contract was terminated on the date of the Greenwood Drop-Down. During the three months ended March 31, 2020, we purchased $9.9 million of wood pellets from Greenwood and recorded a cost of cover deficiency fee of approximately $0.4 million as Greenwood was unable to satisfy certain commitments. As of March 31, 2020, of the net purchased amount of $9.5 million related to the Greenwood contract, $8.4 million was included in cost of goods sold and $1.1 million was included in finished goods inventory. Holdings TSA Prior to its termination on the date of the Greenwood Drop-Down, we were party to a long-term terminal services agreement with our sponsor (the “Holdings TSA”). The Holdings TSA was amended and assigned to Greenwood and provided for deficiency payments if quarterly minimum throughput requirements were not met. During the three months ended March 31, 2020, we recorded $0.6 million of deficiency fees from Greenwood, which was included in other revenue. Enviva FiberCo, LLC We purchase raw materials from Enviva FiberCo, LLC (“FiberCo”), a wholly owned subsidiary of our sponsor, including through a wood supply agreement that provided for deficiency fees in the event FiberCo did not satisfy certain volume commitments. Purchased raw materials net of cost of cover deficiency fees are included in cost of goods sold. Raw materials purchased during the three months ended March 31, 2021 were $6.0 million. No cost of cover deficiency fees were recognized during the three months ended March 31, 2021. During the three months ended March 31, 2020, included in cost of goods sold was $1.4 million of raw materials purchased. As of March 31, 2021, related-party payables of $0.8 million is included in related-party payables related to raw materials purchased from FiberCo.

Partners' Capital Notes [Abstract]
Partners' Capital	Partners’ Capital Allocations of Net Income (Loss) Our partnership agreement contains provisions for the allocation of net income and loss to our unitholders and Enviva Partners GP, LLC (the “General Partner”), a wholly owned subsidiary of our sponsor. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss shall be allocated among the partners of the Partnership in accordance with their respective percentage ownership interest. Such allocations are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions, which are allocated 100% to the holder of our incentive distribution rights (“IDRs”). Prior to the Hamlet Drop-Down, John Hancock had received all of its capital contributions and substantially all of its preference amount and the historical net losses of the Hamlet JV had been allocated to the members of the Hamlet JV in proportion to their unreturned capital contributions; consequently, the balance of members’ capital attributable to John Hancock was negative at the time of the Hamlet Drop-Down. We have not received full repayment of revolving borrowings from the Hamlet JV pursuant to the Hamlet JV Revolver or its capital contributions and full preference amount as of March 31, 2021; as a result, none of the earnings of the Hamlet JV have been allocated to John Hancock following the Hamlet Drop-Down and no change has been recognized to the negative noncontrolling interest balance attributable to John Hancock that we acquired. Incentive Distribution Rights IDRs represent the right to receive increasing percentages (from 15.0% to 50.0%) of quarterly distributions from operating surplus after we achieve distributions in amounts exceeding specified target distribution levels. Our sponsor currently holds 100% of our IDRs through its wholly owned subsidiary Enviva MLP Holdco, LLC. Prior to 2021, the IDRs were held by the General Partner, a wholly owned subsidiary of our sponsor. Cash Distributions to Unitholders Distributions that have been paid or declared related to the reporting period are considered in the determination of earnings per unit. The following table details the cash distribution paid or declared (in millions, except per unit amounts): Quarter Ended Declaration Record Payment Distribution Total Cash Total Payment to holder of Incentive Distribution Rights March 31, 2020 April 29, 2020 May 15, 2020 May 29, 2020 $ 0.6800 $ 22.9 $ 3.5 June 30, 2020 August 5, 2020 August 14, 2020 August 28, 2020 $ 0.7650 $ 30.4 $ 7.5 September 30, 2020 October 30, 2020 November 13, 2020 November 27, 2020 $ 0.7750 $ 30.8 $ 7.9 December 31, 2020 January 29, 2021 February 15, 2021 February 26, 2021 $ 0.7800 $ 31.2 $ 8.1 March 31, 2021 April 28, 2021 May 14, 2021 May 28, 2021 $ 0.7850 $ 31.4 $ 8.3 For purposes of calculating our earnings per unit under the two-class method, common units are treated as participating preferred units. IDRs are treated as participating securities. Distributions made in future periods based on the current period calculation of cash available for distribution are allocated to each class of equity that will receive the distribution. Any unpaid cumulative distributions are allocated to the appropriate class of equity. We determine the amount of cash available for distribution for each quarter in accordance with our partnership agreement. The amount to be distributed to unitholders and IDR holders is based on the distribution waterfall set forth in our partnership agreement. Net earnings for the quarter are allocated to each class of partnership interest based on the distributions to be made.

Net Income (Loss) per Limited Partner Unit	Mar. 31, 2021
Earnings Per Share [Abstract]
Net Income (Loss) per Limited Partner Unit	Net Income (Loss) per Limited Partner Unit Net income (loss) per unit applicable to limited partners is computed by dividing limited partners’ interest in net income (loss), after deducting any incentive distributions, by the weighted-average number of outstanding units. Our net income (loss) is allocated to the limited partners in accordance with their respective ownership percentages, after giving effect to priority income allocations for incentive distributions, if any, to the holder of the IDRs, which are declared and paid following the close of each quarter. Earnings in excess of distributions are allocated to the limited partners based on their respective ownership interests. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income (loss) allocations used in the calculation of earnings per unit. In addition to the common units, we have identified the IDRs and phantom units as participating securities and apply the two-class method when calculating the net income (loss) per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Diluted net income per unit includes the effects of potentially dilutive time-based and performance-based phantom units on our common units. The computation of net income (loss) available per limited partner unit is as follows for the three months ended March 31, 2021 and 2020: Three Months Ended March 31, 2021 Three Months Ended March 31, 2020 Common General Common General Weighted-average common units outstanding—basic 39,933 — 33,551 — Effect of nonvested phantom units — — 1,885 — Weighted-average common units outstanding—diluted 39,933 — 35,436 — Three Months Ended March 31, 2021 Common Incentive Distribution Rights Total Distributions declared $ 31,426 $ 8,322 $ 39,748 Earnings less than distributions (42,162) — (42,162) Net (loss) income available to partners $ (10,736) $ 8,322 $ (2,414) Weighted-average units outstanding—basic and diluted 39,933 Net loss per limited partner unit—basic and diluted $ (0.27) Three Months Ended March 31, 2020 Common Incentive Distribution Rights Total Distributions declared $ 22,856 $ 3,457 $ 26,313 Earnings less than distributions (19,503) — (19,503) Net income available to partners $ 3,353 $ 3,457 $ 6,810 Weighted-average units outstanding—basic 33,551 Weighted-average units outstanding—diluted 35,436 Net income per limited partner unit—basic $ 0.10 Net income per limited partner unit—diluted $ 0.09

Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments and accruals necessary for a fair presentation have been included. All such adjustments and accruals are of a normal and recurring nature unless disclosed otherwise. All intercompany balances and transactions have been eliminated in consolidation. The results reported in the financial statements are not necessarily indicative of the results that may be reported for the entire year. The unaudited financial statements and notes should be read in conjunction with the audited financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2020.

Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards On January 1, 2021, we adopted ASU 2019-12- Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which removes certain exceptions for recognizing deferred taxes for investments, performing intraperiod allocation and calculating income taxes in interim periods. The ASU also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. The adoption did not have a material impact on the financial statements.
