Martin Midstream Partners L.P. (the "Partnership") is a publicly traded limited partnership with a diverse set of operations focused primarily in the United States ("U.S.") Gulf Coast region. Its 4 primary business lines include:   terminalling, processing, storage and packaging services for petroleum products and by-products including the refining of naphthenic crude oil; land and marine transportation services for petroleum products and by-products, chemicals, and specialty products; sulfur and sulfur-based products processing, manufacturing, marketing and distribution; and natural gas liquids marketing, distribution, and transportation services.
 
The Partnership’s unaudited consolidated and condensed financial statements have been prepared in accordance with the requirements of Form 10-Q and U.S. Generally Accepted Accounting Principles ("U.S. GAAP") for interim financial reporting. Accordingly, these financial statements have been condensed and do not include all of the information and footnotes required by U.S. GAAP for annual audited financial statements of the type contained in the Partnership’s annual reports on Form 10-K. In the opinion of the management of the Partnership’s general partner, all adjustments and elimination of significant intercompany balances necessary for a fair presentation of the Partnership’s financial position, results of operations, and cash flows for the periods shown have been made. All such adjustments are of a normal recurring nature. Results for such interim periods are not necessarily indicative of the results of operations for the full year. These financial statements should be read in conjunction with the Partnership’s audited consolidated financial statements and notes thereto included in the Partnership’s annual report on Form 10-K for the year ended December 31, 2019,2020, filed with the Securities and Exchange Commission (the "SEC")SEC on February 14, 2020.March 3, 2021.

Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these consolidated and condensed financial statements in conformity with U.S. GAAP.  Actual results could differ from those estimates.

Divestiture of Natural Gas Storage Assets. On June 28, 2019, the Partnership completed the sale of its membership interests in Arcadia Gas Storage, LLC, Cadeville Gas Storage LLC, Monroe Gas Storage Company, LLC and Perryville Gas Storage LLC (the "Natural Gas Storage Assets") to Hartree Cardinal Gas, LLC ("Hartree"), a subsidiary of Hartree Bulk Storage, LLC. The Natural Gas Storage Assets consist of approximately 50 billion cubic feet of working capacity located in northern Louisiana and Mississippi. In consideration of the sale of the Natural Gas Storage Assets, the Partnership received cash proceeds of $210,067 after transaction fees and expenses. The net proceeds were used to reduce outstanding borrowings under the Partnership's revolving credit facility. The Partnership concluded the disposition represented a strategic shift which had a major effect on its financial results going forward. As a result, the Partnership has presented the results of operations and cash flows relating to the Natural Gas Storage Assets as discontinued operations for the three months ended March 31, 2019. See Note 3 for more information.

Impact of COVID-19 Pandemic. A novel strain of coronavirus (“COVID-19”) surfaced in late 2019 and has spread around the world, including to the United States. In March 2020, the World Health Organization declared COVID-19 a pandemic. Due to the economic impacts of the COVID-19 pandemic, the markets have experienced a decline in oil prices in response to oil demand concerns. These concerns have been further exacerbated by the price war among members of the Organization of Petroleum Exporting Countries and other non-OPEC producer nations during the first quarter 2020 and global storage considerations. Travel restrictions and stay-at-home orders implemented by governments in many regions and countries across the globe, including the United States, have greatly impacted the demand for refined products resulting in a significant reduction in refinery utilization.

The COVID-19 pandemic has impacted the Partnership's 2020 performance to date, and the Partnership expects to continue to experience the impacts of COVID-19 throughout the remainder of 2020 as a result of continued reduction in refined product demand across the industries the Partnership serves. The extent to which the duration and severity of the pandemic impacts our business, results of operations, and financial condition, will depend on future developments, which are highly uncertain and cannot be predicted at this time. Accordingly, it is possible that the impact of the COVID-19 pandemic could have a material adverse effect on the Partnership's results of operations, financial position and cash flows for the year ended December 31, 2020, including the recoverability of long-lived assets and goodwill, the valuation of inventory, and the amount of expected credit losses.

Management considered the impact of the COVID-19 pandemic on the assumptions and estimates used in the preparation of the financial statements. Management identified triggering events requiring the performance of impairment testing of long-lived assets and goodwill related to both the performance the Partnership's unit price during the first quarter of 2020 and certain of the Partnership's businesses that are sensitive to reductions in refined product demand and refinery utilization. As a result, the Partnership recorded impairment charges of $4.4 million related to long-lived assets. See Note 3 for more information. No impairments were identified related to goodwill. A sustained reduction in refinery demand and utilization could lead to future asset impairments as well as adversely affect access to capital and financing to be able to meet future obligations. Management also assessed the extent to which the current macroeconomic events brought about by COVID-19 and significant declines in refined product demand impacted the valuation of expected credit losses on accounts receivable and certain inventory items or resulted in modifications to any significant contracts. Ultimately the results of these assessments did not have a material impact on the Partnership's results as of March 31, 2020.

NOTE 2. NEW ACCOUNTING PRONOUNCEMENTS

During the first quarter of 2020,On January 1, 2021, the Partnership adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update (“ASU”("ASU") 2016-13, "Financial Instruments - Credit Losses,"2019-12, Income Taxes (Accounting Standards Codification ("ASC") Topic 740): Simplifying the Accounting for Income Taxes, which required the Partnershipremoves certain exceptions to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions,general principles in ASC 740 and reasonable supportable forecasts. This replaced theclarifies and amends existing incurred loss model and is applicable to the measurement of credit losses on financial assets, including trade receivables.guidance within U.S. GAAP. Adoption of the new standard did not have a material impact on the Partnership’s consolidated financial statements.

NOTE 3. DIVESTITURES AND DISCONTINUED OPERATIONS
Divestiture of Natural Gas Storage Assets. On June 28, 2019, the Partnership completed the sale of the Natural Gas Storage Assets to Hartree, a subsidiary of Hartree Bulk Storage, LLC. The Natural Gas Storage Assets consist of approximately 50 billion cubic feet of working capacity located in northern Louisiana and Mississippi. In consideration of the sale of these assets, the Partnership received cash proceeds of $210,067 after transaction fees and expenses. The net proceeds were used to reduce outstanding borrowings under the Partnership's revolving credit facility. The Partnership has concluded the disposition represents a strategic shift and will have a major effect on its financial results going forward. As a result, the Partnership has presented the results of operations and cash flows relating to the Natural Gas Storage Assets as discontinued operations for the three months ended March 31, 2019.

The operating results, which are included in income from discontinued operations, were as follows:

NOTE 3. REVENUE
Long-Lived Assets Held for Sale

At December 31, 2019, certain terminalling and storage and transportation assets met the criteria to be classified as held for sale in accordance with ASC 360-10 and are presented at the lower of the assets' carrying amount or fair value less cost to sell by segment in current assets in the table below. These assets are considered non-core assets to the Partnership's operations and did not qualify for discontinued operations presentation under the guidance of ASC 205-20.

Revenue is measured based on a consideration specified in a contract with a customer and excludes amounts collected on behalf of third parties where the Partnership is acting as an agent. The Partnership recognizes revenue when the Partnership satisfies a performance obligation, which typically occurs when the Partnership transfers control over a product to a customer or as the Partnership delivers a service.

The following is a description of the principal activities - separated by reportable segments - from which the Partnership generates revenue.

Terminalling and Storage Segment

Revenue is recognized for storage contracts based on the contracted monthly tank fixed fee.  For throughput contracts, revenue is recognized based on the volume moved through the Partnership’s terminals at the contracted rate.  For the Partnership’s tolling agreement, revenue is recognized based on the contracted monthly reservation fee and throughput volumes moved through the facility.  When lubricants and drilling fluids are sold by truck or rail, revenue is recognized when title is transferred, which is either upon delivering product to the customer or when the product leaves the Partnership's facility, depending on the specific terms of the contract. Delivery of product is invoiced as the transaction occurs and is generally paid within a month. Throughput and storage revenue in the table above includes non-cancelable revenue arrangements that are under the scope of ASC 842, whereby the Partnership has committed certain Terminalling and Storage assets in exchange for a minimum fee.

Natural Gas Liquids Segment

NGL distribution    Natural Gas Liquids ("NGL") revenue is recognized when product is delivered by truck, rail, or pipeline to the Partnership's NGL customers. Revenue is recognized on title transfer of the product to the customer. Delivery of product is invoiced as the transaction occurs and is generally paid within a month.

4 As of March 31, 2020, the Partnership’s 7.25% senior unsecured notes due 2021 (the "2021 Notes") were due within twelve months and have therefore been presented as a current liability on the Consolidated and Condensed Balance Sheets at March 31, 2020.  The Partnership's amended revolving credit facility includes a provision which accelerates the maturity date to August 19, 2020 if the 2021 Notes are not refinanced in a manner not prohibited by the facility. If the Partnership is unable to refinance the 2021 Notes and is unable to repay the outstanding borrowings under its revolving credit facility on August 19, 2020, the Partnership's ability to meet its obligations would be adversely affected. Failure to comply with this provision, if not waived, would result in an event of default under the Partnership's revolving credit facility, the potential acceleration of outstanding debt thereunder, and the potential foreclosure on the collateral securing such debt, and could cause a cross-default under other agreements, which could also result in the acceleration of those obligations by the counterparties to those agreements. The Partnership, with support from the Board of Directors, is actively pursuing a variety of strategic alternatives to strengthen the balance sheet and address near term maturities and accordingly, announced on April 6, 2020, the hiring of Stephens Inc. as a financial advisor to assist in the process. Pending the successful implementation of the refinancing, the conditions described above have raised substantial doubt about the Partnership’s ability to continue as a going concern.  The Partnership’s management is engaged in ongoing communication with credit providers and presently believes the measures being taken will enable the Partnership to successfully refinance the 2021 Notes and comply with covenants under its revolving credit facility, although no assurance can be given.

5 In March 2020, the Partnership repurchased on the open market an aggregate $9,344 of the 2021 Notes. These transactions resulted in a gain on retirement of $3,484.

The Partnership paid cash interest, net of capitalized interest, in the amount of $16,736 and $19,363 for the three months ended March 31, 2020 and 2019, respectively.  Capitalized interest was $4 and $2 for the three months ended March 31, 2020 and 2019, respectively.

NOTE 7.6. LEASES
    
The Partnership has numerous operating leases primarily for terminal facilities and transportation and other equipment. The leases generally provide that all expenses related to the equipment are to be paid by the lessee.

Operating lease Right-of-Use ("ROU") assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. Because most of the Partnership's leases do not provide an implicit rate of return, the Partnership uses its imputed collateralized rate based on the information available at commencement date in determining the present value of lease payments. The estimated rate is based on a risk-free rate plus a risk-adjusted margin.

Our leases have remaining lease terms of 1 year to 1716 years, some of which include options to extend the leases for up to 5 years, and some of which include options to terminate the leases within 1 year. The Partnership includes extension periods and excludes termination periods from its lease term if, at commencement, it is reasonably likely that the Partnership will exercise the option.

NOTE 9.8. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Partnership’s revenues and costresults of products sold areoperations could be materially impacted by changes in NGL prices. Additionally, the Partnership's results of operations are materially impacted by changes incommodity prices and interest rates. In an effort to manage its exposure to these risks, the Partnership periodically enters into various derivative instruments, including commodity and interest rate hedges. All derivatives and hedging instruments are non-hedge derivatives and are included on the balance sheet as an asset or a liability measured at fair value, and changes in fair value are recognized as gains and losses in the earnings of the periods in which they occur.

(a)    Commodity Derivative Instruments

The Partnership from time to time has used derivatives to manage the risk of commodity price fluctuation. Commodity risk is the adverse effect on the value of a liability or future purchase that results from a change in commodity price.  The Partnership has established a hedging policy and monitors and manages the commodity market risk associated with potential commodity risk exposure.  In addition, the Partnership has focused on utilizing counterparties for these transactions whose financial condition is appropriate for the credit risk involved in each specific transaction. The Partnership has entered into hedging transactions as of March 31, 20202021, to protect a portion of its commodity price risk exposure. These hedging arrangements are in the form of swaps for NGLs. At March 31, 2020, the Partnership has instruments totaling a gross notional quantity of 25,000 barrels settling during the month of April 2020. At December 31, 2019,2021, the Partnership had instruments totaling a gross notional quantity of 452,000225,000 barrels settling during the period from April 30, 2021 through June 30, 2021. At December 31, 2020, the Partnership had instruments totaling a gross notional quantity of 137,000 barrels settling during the period from January 31, 20202021 through February 29, 2020.28, 2021. These instruments settle against the applicable pricing source for each grade and location.

(b)    Interest Rate Derivative Instruments

The Partnership is exposed to market risks associated with interest rates. Market risk is the adverse effect on the value of a financial instrument that results from a change in interest rates. We minimize this market risk by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken. From time to time, the Partnership enters into interest rate swaps to manage interest rate risk associated with the Partnership’s variable rate credit facility and its 2021 Notes. At March 31, 2020 and December 31, 2019, the Partnership did not have any outstanding interest rate derivative instruments.

NOTE 10.9. PARTNERS' CAPITAL

As of March 31, 2020,2021, Partners’ capital consisted of 38,852,50738,802,750 common limited partner units, representing a 98% partnership interest, and a 2% general partner interest. Martin Resource Management Corporation, through subsidiaries, owns 6,114,532 of the Partnership's common limited partner units representing approximately 15.7%15.8% of the Partnership's outstanding common limited partner units. Martin Midstream GP LLC ("MMGP"), the Partnership's general partner, owns the 2% general partnership interest. Martin Resource Management Corporation controls the Partnership's general partner, by virtue of its 51% voting interest in MMGP Holdings, LLC ("Holdings"), the sole member of the Partnership's general partner.

The partnership agreement of the Partnership (the "Partnership Agreement") contains specific provisions for the allocation of net income and losses to each of the partners for purposes of maintaining their respective partner capital accounts.

Impact on Partners Capital (Deficit) Related to Transactions Between Entities Under Common Control

Under ASC 805, assets and liabilities transferred between entities under common control are accounted for at the historical cost of those entities' ultimate parent, in a manner similar to a pooling of interests. Any difference in the amount paid by the transferee versus the historical cost of the assets transferred is recorded as an adjustment to equity (contribution or distribution) by the transferee. This is in contrast with a business combination between unrelated parties, where assets and liabilities are recorded at their fair values at the acquisition date, with any excess of amounts paid over the fair value representing goodwill. From time to time, the most recent being in 2019, the Partnership has entered into common control acquisitions from Martin Resource Management Corporation. The consideration transferred totaling $550,773 exceeds the historical cost of the net assets received. This excess of the purchase price over the historical cost of the net assets received has resulted in cumulative distributions of $287,734 reflected as reductions to Partners' capital.

Incentive Distribution Rights

MMGP holds a 2% general partner interest and certain incentive distribution rights ("IDRs") in the Partnership. IDRs are a separate class of non-voting limited partner interest that may be transferred or sold by the general partner under the terms of the Partnership Agreement, and represent the right to receive an increasing percentage of cash distributions after the minimum quarterly distribution and any cumulative arrearages on common units once certain target distribution levels have been achieved. The Partnership is required to distribute all of its available cash from operating surplus, as defined in the Partnership Agreement. The general partner was allocated 0 incentive distributions during the three months ended March 31, 20202021 and 2019.2020.
 
The target distribution levels entitle the general partner to receive 2% of quarterly cash distributions from the minimum of $0.50 per unit up to $0.55 per unit, 15% of quarterly cash distributions in excess of $0.55 per unit until all unitholders have received $0.625 per unit, 25% of quarterly cash distributions in excess of $0.625 per unit until all unitholders have received $0.75 per unit and 50% of quarterly cash distributions in excess of $0.75 per unit.

Distributions of Available Cash

The Partnership distributes all of its available cash (as defined in the Partnership Agreement) within 45 days after the end of each quarter to unitholders of record and to the general partner. Available cash is generally defined as all cash and cash equivalents of the Partnership on hand at the end of each quarter less the amount of cash reserves its general partner determines in its reasonable discretion is necessary or appropriate to: (i) provide for the proper conduct of the Partnership’s business; (ii) comply with applicable law, any debt instruments or other agreements; or (iii) provide funds for distributions to unitholders and the general partner for any one or more of the next four quarters, plus all cash on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.

Net Income per Unit

The Partnership follows the provisions of the FASB ASC 260-10 related to earnings per share, which addresses the application of the two-class method in determining income per unit for master limited partnerships having multiple classes of securities that may participate in partnership distributions accounted for as equity distributions. Undistributed earnings are allocated to the general partner and limited partners utilizing the contractual terms of the Partnership Agreement. Distributions to the general partner pursuant to the IDRs are limited to available cash that will be distributed as defined in the Partnership Agreement. Accordingly, the Partnership does not allocate undistributed earnings to the general partner for the IDRs because the general partner's share of available cash is the maximum amount that the general partner would be contractually entitled to receive if all earnings for the period were distributed. When current period distributions are in excess of earnings, the excess distributions for the period are to be allocated to the general partner and limited partners based on their respective sharing of income and losses specified in the Partnership Agreement. Additionally, as required under FASB ASC 260-10-45-61A, unvested share-based payments that entitle employees to receive non-forfeitable distributions are considered participating securities, as defined in FASB ASC 260-10-20, for earnings per unit calculations.

For purposes of computing diluted net income per unit, the Partnership uses the more dilutive of the two-class and if-converted methods. Under the if-converted method, the weighted-average number of subordinated units outstanding for the period is added to the weighted-average number of common units outstanding for purposes of computing basic net income per unit and the resulting amount is compared to the diluted net income per unit computed using the two-class method. The following is a reconciliation of net income from continuing operations and net income from discontinued operations allocated to the general partner and limited partners for purposes of calculating net income attributable to limited partners per unit:

All outstanding units were included in the computation of diluted earnings per unit and weighted based on the number of days such units were outstanding during the periods presented. All common unit equivalents were antidilutive for the three months ended March 31, 2019 because the limited partners were allocated a net loss in this period.

NOTE 11.10. UNIT BASED AWARDS

The Partnership recognizes compensation cost related to unit-based awards to both employees and non-employees in its consolidated and condensed financial statements in accordance with certain provisions of ASC 718. Amounts recognized in selling, general, and administrative expense in the consolidated and condensed financial statements with respect to these plans are as follows:
Three Months Ended March 31,
20212020
Employees$194 $301 
Non-employee directors46 45 
   Total unit-based compensation expense$240 $346

 2020 2019
Employees$301
 $329
Non-employee directors45
 23
   Total unit-based compensation expense$346
 $352


All of the Partnership's outstanding awards at March 31, 20202021 met the criteria to be treated under equity classification.

Long-Term Incentive Plans
    
      The Partnership's general partner has a long-term incentive plan for employees and directors of the general partner and its affiliates who perform services for the Partnership.
On May 26, 2017, the unitholders of the Partnership approved the Martin Midstream Partners L.P. 2017 Restricted Unit Plan (the "2017 LTIP"). The plan currently permits the grant of awards covering an aggregate of 3,000,000 common units, all of which can be awarded in the form of restricted units. The plan is administered by the compensation committee of the general partner’s board of directors (the "Compensation Committee").
 A restricted unit is a unit that is granted to grantees with certain vesting restrictions, which may be time-based and/or performance-based. Once these restrictions lapse, the grantee is entitled to full ownership of the unit without restrictions. The Compensation Committee may determine to make grants under the plan containing such terms as the Compensation Committee shall determine under the plan. With respect to time-based restricted units ("TBRU's"), the Compensation Committee will determine the time period over which restricted units granted to employees and directors will vest. The Compensation Committee may also award a percentage of restricted units with vesting requirements based upon the achievement of specified pre-established performance targets ("Performance Based Restricted Units" or "PBRU's"). The performance targets may include, but are not limited to, the following: revenue and income measures, cash flow measures, net income before interest expense and income tax expense ("EBIT"), net income before interest expense, income tax expense, and depreciation and amortization ("EBITDA"), distribution coverage metrics, expense measures, liquidity measures, market measures, corporate sustainability metrics, and other measures related to acquisitions, dispositions, operational objectives and succession planning objectives. PBRU's are earned only upon our achievement of an objective performance measure for the performance period. PBRU's which vest are payable in common units.  Unvested units granted under the 2017 LTIP may or may not participate in cash distributions depending on the terms of each individual award agreement.

The performance conditions related to the PBRU's awarded on March 1, 2018 were not achieved and the Partnership, as such, did not recognize compensation expense for the vesting of the units.

The restricted units issued to directors generally vest in equal annual installments over a four-year period. Restricted units issued to employees generally vest in equal annual installments over three years of service.

In February 2020,2021, the Partnership issued 27,00014,056 TBRU's to each of the Partnership's 3 independent directors under the 2017 LTIP.  These restricted common units vest in equal installments of 6,7503,514 units on January 24, 2021, 2022, 2023, 2024, and 2024.2025.

19
On March 1, 2018, the Partnership issued 301,550 TBRU's and 317,925 PBRU's to certain employees of Martin Resource Management Corporation. The TBRU's vest in equal installments over a three-year service period. The PBRU's will vest at the conclusion of a three-year performance period based on certain performance targets. In addition, the PBRU's awarded on March 1, 2018 that are achieved will only vest if the grantee is employed by Martin Resource Management Corporation on March 31, 2021. As of March 31, 2020, the Partnership is unable to ascertain if certain performance conditions will be achieved and, as such, has not recognized compensation expense for the vesting of the units. The Partnership will record

As of March 31, 2020,2021, there was $1,613$395 of unrecognized compensation cost related to non-vested restricted units. That cost is expected to be recognized over a weighted-average period of 1.512.59 years.

NOTE 12.11. RELATED PARTY TRANSACTIONS

As of March 31, 2020,2021, Martin Resource Management Corporation owns 6,114,532 of the Partnership’s common units representing approximately 15.7%15.8% of the Partnership’s outstanding limited partner units.  Martin Resource Management Corporation controls the Partnership's general partner by virtue of its 51% voting interest in Holdings, the sole member of the Partnership's general partner. The Partnership’s general partner, MMGP, owns a 2% general partner interest in the Partnership and the Partnership’s IDRs.  The Partnership’s general partner’s ability, as general partner, to manage and operate the Partnership, and Martin Resource Management Corporation’s ownership as of March 31, 2020,2021, effectively gives Martin Resource Management Corporation the ability to veto some of the Partnership’s actions and to control the Partnership’s management.

NOTE 14. COMMITTMENTS13. COMMITMENTS AND CONTINGENCIES

Contingencies

From time to time, the Partnership is subject to various claims and legal actions arising in the ordinary course of business.  In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Partnership.
    
On December 31, 2015, the Partnership received a demand from a customer in its lubricants packaging business for defense and indemnity in connection with lawsuits filed against it in various United States District Courts, which generally allege that the customer engaged in unlawful and deceptive business practices in connection with its marketing and advertising of its private label motor oil.  The Partnership disputes that it has any obligation to defend or indemnify the customer for its conduct.  Accordingly, on January 7, 2016, the Partnership filed a Complaint for Declaratory Judgment in the Chancery Court of Davidson County, Tennessee requesting a judicial determination that the Partnership does not owe the customer the demanded defense and indemnity obligations.  The lawsuits against the customer have been transferred to the United States

District Court for the Western District of Missouri for consolidated pretrial proceedings.  On March 1, 2017, at the request of the parties, the Chancery Court of Davidson County, Tennessee administratively closed the Partnership's lawsuit pending rulings in the United States District Court for the Western District of Missouri.  In the event that either party moves the Chancery Court of Davidson County, Tennessee to reopen the case, we expect the Court would grant such motion and reopen the case.  Further, the same customer has made a claim under the Partnership’s insurance policy.  The insurer has denied the claim.  However, in the event that the customer is successful in pursuing the claim, such action would negatively impact the Partnership because the Partnership hasmay have certain reimbursement obligations it would owe the insurance company.  If the case is reopened or the insurance claim by the customer is successful, we are currently unable to determine the exposure we may have in this matter, if any.

NOTE 15.14. FAIR VALUE MEASUREMENTS

The Partnership uses a valuation framework based upon inputs that market participants use in pricing certain assets and liabilities. These inputs are classified into two categories: observable inputs and unobservable inputs. Observable inputs represent market data obtained from independent sources. Unobservable inputs represent the Partnership's own market assumptions. Unobservable inputs are used only if observable inputs are unavailable or not reasonably available without undue cost and effort. The two types of inputs are further prioritized into the following hierarchy:

Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market basedmarket-based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that reflect the entity's own assumptions and are not corroborated by market data.

The Partnership is required to disclose estimated fair values for its financial instruments. Fair value estimates are set forth below for these financial instruments. The following methods and assumptions were used to estimate the fair value of each class of financial instrument:

Accounts and other receivables, trade and other accounts payable, accrued interest payable, other accrued liabilities, income taxes payable and due from/to affiliates: The carrying amounts approximate fair value due to the short maturity and highly liquid nature of these instruments, and as such these have been excluded from the table below. There is negligible credit risk associated with these instruments.

Current and noncurrentnon-current portion of long-term debt: The carrying amount of the revolving credit facility approximates fair value due to the debt having a variable interest rate and is in Level 2. The Partnership has not had any indicators which represent a change in the market spread associated with its variable interest rate debt. The estimated fair value of the 2021 Notes, 2024 Notes, and 2025 Notes (collectively, the "Senior Notes") is considered Level 1, as the fair value is based on quoted market prices in active markets.

The increasedecrease in the effective income tax rate for the income taxes during the three months ended March 31, 2020,2021, compared to the three months ended March 31, 2019,2020, is primarily due to an increase in permanent differences and a decrease in income before income taxes.permanent differences. The decrease in the provision for income taxes during the three months ended March 31, 2020,2021, compared to the similar period in 2019,2020, was primarily due to the impact of a decrease in income before income taxes in the current period.

The Coronavirus Aid, Relief, and Economic Security ("CARES") Act was enacted on March 27, 2020, in response to the market volatility and instability resulting from the COVID-19 pandemic, and includes changes to various income tax provisions including, but not limited to, providing for a five-year carryback of net operating losses generated in taxable years beginning after December 31, 2017, and before January 1, 2021, suspension of the 80% taxable income limitation for net operating losses generated after December 31, 2017, and before January 1, 2021, and relaxation of the limitation of adjusted taxable income as determined under Internal Revenue Code Section 163(j) from 30% to 50% when determining the deduction for business interest expense for 2019 and 2020. Since, prior to its acquisition by the Partnership, MTI was a Qualified Subchapter S subsidiary ("QSub") of Martin Resource Management Corporation, it is precluded from carrying back net operating losses to its QSub taxable years. The other applicable provisions of the CARES Act have no material impact on the annual effective tax rate ("AETR"), deferred taxes, or valuation allowances.

A current federal income tax expense (benefit) of $133$15 and $297,$133, related to the operation of the subsidiary,Taxable Subsidiary, were recorded for the three months ended March 31, 20202021 and 2019,2020, respectively. A current state income tax expense (benefit) of $(72)$12 and $(218)$(72), related to the operation of the subsidiary, wereTaxable Subsidiary, was recorded for the three months ended March 31, 2021 and 2020, and 2019, respectivelyrespectively.

With respect to MTI, income taxes are accounted for under the asset and liability method pursuant to the provisions of ASC 740 related to income taxes. 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.

A deferred tax expense related to the MTI temporary differences of $286$75 and $369$286 was recorded for the three months ended March 31, 20202021 and 2019,2020, respectively. A net deferred tax asset of $23,136$22,178 and $23,422,$22,253, related to the cumulative book and tax temporary differences, existed at March 31, 20202021 and December 31, 2019,2020, respectively.

All income tax positions taken for all open years are more likely than not to be sustained based upon their technical merit under applicable tax laws.

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion of our financial condition and results of operations in conjunction with the consolidated and condensed financial statements and the notes thereto included elsewhere in this quarterly report.

Overview
 
We are a publicly traded limited partnership with a diverse set of operations focused primarily in the U.S. Gulf Coast region. Our four primary business lines include:

Terminalling, processing, storage and packaging services for petroleum products and by-products including the refining of naphthenic crude oil;

Land and marine transportation services for petroleum products and by-products, chemicals, and specialty products;

Sulfur and sulfur-based products processing, manufacturing, marketing, and distribution; and

NGL marketing, distribution, and transportation services.

The petroleum products and by-products we collect, transport, store and market are produced primarily by major and independent oil and gas companies who often turn to third parties, such as us, for the transportation and disposition of these products. In addition to these major and independent oil and gas companies, our primary customers include independent refiners, large chemical companies, and other wholesale purchasers of these products. We operate primarily in the U.S. Gulf Coast region. This region is a major hub for petroleum refining, natural gas gathering and processing, and support services for the exploration and production industry.

We were formed in 2002 by Martin Resource Management Corporation, a privately-held company whose initial predecessor was incorporated in 1951 as a supplier of products and services to drilling rig contractors. Since then, Martin Resource Management Corporation has expanded its operations through acquisitions and internal expansion initiatives as its management identified and capitalized on the needs of producers and purchasers of petroleum products and by-products and other bulk liquids. Martin Resource Management Corporation is an important supplier and customer of ours. As of March 31, 2020,2021, Martin Resource Management Corporation owned 15.7%15.8% of our total outstanding common limited partner units. Furthermore, Martin Resource Management Corporation controls Martin Midstream GP LLC ("MMGP"), our general partner, by virtue of its 51% voting interest in MMGP Holdings, LLC ("Holdings"), the sole member of MMGP. MMGP owns a 2.0% general partner interest in us and all of our incentive distribution rights. Martin Resource Management Corporation directs our business operations through its ownership interests in and control of our general partner.

We entered into an omnibus agreement dated November 1, 2002, with Martin Resource Management Corporation (the "Omnibus Agreement")the Omnibus Agreement that governs, among other things, potential competition and indemnification obligations among the parties to the agreement, related party transactions, the provision of general administration and support services by Martin Resource Management Corporation and our use of certain of Martin Resource Management Corporation’s trade names and trademarks. Under the terms of the Omnibus Agreement, the employees of Martin Resource Management Corporation are responsible for conducting our business and operating our assets.

Martin Resource Management Corporation has operated our business since 2002.  Martin Resource Management Corporation began operating our NGL business in the 1950s and our sulfur business in the 1960s. It began our land transportation business in the early 1980s and our marine transportation business in the late 1980s. It entered into our fertilizer and terminalling and storage businesses in the early 1990s.

Significant Recent Developments

COVID-19 Pandemic

The Partnership prioritizes the health and safety of our employees, the businessesWinter Storm Uri. In February 2021, we serve,experienced Winter Storm Uri ("Uri"), an unprecedented storm bringing extreme cold temperatures to Texas and the communitiessurrounding areas, which resulted in gulf coast refineries running at reduced rates or halting operations entirely. The majority of the impact we experienced was centered around our transportation and sulfur services segments where we live and work. To support the safety of all ofsaw reduced activity due to Uri's impact on Gulf Coast refinery utilization. Additionally, our employees and operations, precautionary measures have been implementedSmackover Refinery was down approximately nine days due to prevent the COVID-19 virus from spreading in our workplace or the locations we serve, including suspending non-essential travel, limiting the number of employees attending meetings, reducing the number of people at our locations at any oneUri, during which time monitoring the health of all employees, and implementing work-from-home initiatives for all eligible employees.

Further, we began awareness trainingpreparations for allthe

This allowed us to minimize the amount of downtime at the Smackover Refinery which was back in or around our docks, vessels, and trucks and locationsoperation by March 9, 2021.

COVID-19. We continue to which they are delivering. Our communication lines are open 24/7 formonitor the environmental health and safety division, land and marine logistics, and sales and marketing teams.

Due to the economic impacts of the COVID-19 pandemic the markets have experienced a decline in oil prices in response to oil demand concerns. These concerns have been further exacerbated by the price war among memberson all aspects of the Organization of Petroleum Exporting Countries and other non-OPEC producer nations during the first quarter 2020 and global storage considerations.our business. Travel restrictions and stay-at-home orders implemented by governments in many regions and countries across the globe, including the United States,U.S., have greatly impacted the demand for refined products resulting in a significant reduction in refinery utilization. The COVID-19 pandemic hasutilization, which impacted our 2020 performance and continues to date. The impact of this outbreak startedour marine and land transportation businesses in February and was more significant in March, during which time we have seen unfavorable trends in certain key metrics across several of our business lines compared to recent periods.

2021.
We
Looking forward, we expect to continue to experience thesome adverse impacts of COVID-19 onin our business throughouttransportation segment through the remaindermiddle part of 2020the year but we believe that refinery utilization will continue to increase in the second half of 2021 as a result of an expected continued reduction inwidespread vaccinations, government stimulus, and a rebounding economy. This should ultimately improve refined product demand across the industries we serve. As we look forward inas people generally return to in-person work and resume travel. We expect this will positively impact our Terminalling and Storagetransportation segment there should be minimal impact on the storage component of this business due to minimum volume commitment contracts. However, there is downside risk in our packaged lubricant and grease businesses due to anticipated reduced demand from our oil and gas production customers and our construction customers. In our Transportation segment, reducedas demand for refined products is expected to continue to impact our daily load count specific to our refinery customers in our land transportation business. Our near-term outlook currently remains cautiously optimistic for marine transportation as we are now seeing demand for the use of barges as floating storage for crude oil, which should support barge utilization if refinery barge demand decreases. In our Natural Gas Liquids segment, our butane optimization business could be impacted by reduced butane production out of third-party refineries as they run at lower utilization rates during the economic shutdown. As a result, we are unable to predict the amount of butane volume we are able to purchase and store this summer in order to sell back to refiners during the winter blending season. However, we believe working capital invested in this business will be significantly less than last year, primarily due to depressed energy prices which translates to lower debt levels supporting our butane business in 2020. Looking forward in our Sulfur Services segment, we believe our molten sulfur business will not be affected as we are paid a monthly logistics fee by our primary customer. However, we do believe there will be reduced overall sulfur volumes from third-party refineries, which will negatively impact our prilling volume, reducing our operating fee revenue. We expect, however, to continue to receive our reservation fees regardless of the amount of sulfur volume processed through our prillers.services improves.


TheOverall, the extent to which the duration and severity of the pandemic impacts our business, results of operations, and financial condition, will depend on future developments, which are highly uncertain and cannot be predicted at this time. Accordingly, it is possible that the full impact of COVID-19 will not be reflected in ourthe pandemic could have a material adverse effect on the Partnership's results of operations, financial position and overall financial performance until future periods. In an effort to conserve capitalcash flows for the year ended December 31, 2021 including the recoverability of long-lived assets and goodwill, the valuation of inventory, and the amount of expected credit losses.
Management considered the impact of the pandemic on the assumptions and estimates used in the near-term, we are actively considering, planningpreparation of the financial statements. A sustained reduction in refinery demand and executing expense reduction initiativesutilization could lead to future asset impairments as well as adversely affect access to capital and have electedfinancing to defer certain maintenance and growth capital expenditures until 2021.

be able to meet future obligations. Management also assessed the extent to which the current macroeconomic events brought about by COVID-19the pandemic and significant declines in refined product demand impacted the valuation of expected credit losses on accounts receivable and certain inventory items or resulted in modifications to any significant contracts. Ultimately the results of these assessments did not have a material impact on our results as of March 31, 2020.2021.

Other Recent Developments

BeginningSale of Mega Lubricants. On December 22, 2020, we entered into an asset purchase and sale agreement to sell certain assets used in July of 2018, we committed to strengthening our balance sheet through strategic initiatives aimed at reducing leverage by divesting non-core assets and businesses, creating the ability to focus on a streamlined corporate strategy and position the Partnership for growth.

The first set of initiatives was executed in 2018 with the divestiture of our 20% interest in West Texas LPG Pipeline Limited Partnership for $195.0 million and the sale of a non-strategic terminal asset located in Nevada for $8.0 million. On January 1, 2019, we completed the next initiative with the acquisition of Martin Transport, Inc. from Martin Resource Management Corporation for $135.0 million, positioning us for cash flow growth. On July 1, 2019, we completed the sale of our natural gas storage assets for $215.0 million, which was an important piece of the Partnership’s strategy to strengthen the balance sheet and re-focus our operational expertise on the refinery services industry. On August 12, 2019, we completed the sale of our East Texas Pipeline for $17.5 million.


As a result of dispositions, offset by acquisitions, we were able to pay down $300.5 million of outstanding debt while incurring only a slight reduction to projected EBITDA. Consistentconnection with our strategyMega Lubricants shore-based terminals business ("Mega Lubricants") to John W. Stone Oil Distributor, LLC ("Stone Oil") for $22.4 million. Mega Lubricants is engaged in the business of reducing leverageblending, manufacturing and improving liquidity,delivering various marine application lubricants, sub-sea specialty fluids, and proprietary commercial and industrial products. The transaction closed on January 28, 2020, we announced a $0.75 per unit reduction ofDecember 22, 2020. The proceeds from the transaction were used to reduce outstanding borrowings under our cash distribution on an annual basis, allowing us to retain $29.2 million to continue to strengthen our balance sheet.revolving credit facility.
          
Subsequent Events

Quarterly Distribution. On April 22, 2020,21, 2021, we declared a quarterly cash distribution of $0.0625$0.005 per common unit for the first quarter of 2020,2021, or $0.25$0.020 per common unit on an annualized basis, which will be paid on May 15, 202014, 2021 to unitholders of record as of May 8, 2020.7, 2021.

Critical Accounting Policies and Estimates    

Our discussion and analysis of our financial condition and results of operations are based on the historical consolidated and condensed financial statements included elsewhere herein. We prepared these financial statements in conformity with United States generally accepted accounting principles U.S. GAAP.

How We Evaluate Our Operations

Our management uses a variety of financial and operational measurements other than our financial statements prepared in accordance with U.S. GAAP to analyze our performance. These include: (1) net income before interest expense, income tax expense, and depreciation and amortization ("EBITDA"), (2) adjusted EBITDA, and (3) distributable cash flow and (4) adjusted free cash flow. Our management views these measures as important performance measures of core profitability for our operations and the ability to generate and distribute cash flow, and as key components of our internal financial reporting. We believe investors benefit from having access to the same financial measures that our management uses.

EBITDA and Adjusted EBITDA. We define Adjusted EBITDA as EBITDA before unit-based compensation expenses, gains and losses on the disposition of property, plant and equipment, impairment and other similar non-cash adjustments. Certain items excluded from EBITDA and adjusted EBITDA are significant components in understanding and assessing an entity's financial performance, such as cost of capital and historical costs of depreciable assets. We have included information concerning EBITDA and adjusted EBITDA because they provideit provides investors and management with additional information to better understand the following: financial performance of our assets without regard to financing methods, capital structure or historical cost basis; our operating performance and return on capital as compared to those of other similarly situated entities; and the viability of acquisitions and capital expenditure projects. Our method of computing adjusted EBITDA may not be the same method used to compute similar measures reported by other entities. The economic substance behind our use of adjusted EBITDA is to measure the ability of our assets to generate cash sufficient to pay interest costs, support our indebtedness and make distributions to our unit holders.unitholders.

Distributable Cash FlowFlow.. We define Distributable Cash Flow as Adjusted EBITDA less cash paid for interest, cash paid for income taxes, maintenance capital expenditures, and plant turnaround costs. Distributable cash flow is a significant performance measure used by our management and by external users of our financial statements, such as investors, commercial banks and research analysts, to compare basic cash flows generated by us to the cash distributions we expectit expects to pay our unitholders. Distributable cash flow is also an important financial measure for our unitholders since it serves as an indicator of our success in providing a cash return on investment. Specifically, this financial measure indicates to investors whether or not we are generating cash flow at a level that can sustain or support an increase in our quarterly distribution rates. Distributable cash flow is also a quantitative standard used throughout the investment community with respect to publicly-traded partnerships because the value of a unit of such an entity is generally determined by the unit's yield, which in turn is based on the amount of cash distributions the entity pays to a unitholder.

Adjusted Free Cash Flow. Adjusted free cash flow is defined as distributable cash flow less growth capital expenditures and principle payments under finance lease obligations. Adjusted free cash flow is a significant performance measure used by our management and by external users of our financial statements and represents how much cash flow a business generates during a specified time period after accounting for all capital expenditures, including expenditures for growth and maintenance capital projects. We believe that adjusted free cash flow is important to investors, lenders, commercial banks and research analysts since it reflects the amount of cash available for reducing debt, investing in additional capital projects, paying distributions, and similar matters. Our calculation of adjusted free cash flow may or may not be comparable to similarly titled measures used by other entities.

EBITDA, adjusted EBITDA, distributable cash flow and distributableadjusted free cash flow should not be considered alternatives to, or more meaningful than, net income, cash flows from operating activities, or any other measure presented in accordance with U.S. GAAP. Our method of computing these measures may not be the same method used to compute similar measures reported by other entities.

Martin Resource Management Corporation allocates to us a portion of its indirect selling, general and administrative expenses for services such as accounting, legal, treasury, clerical, billing, information technology, administration of insurance, engineering, general office expense and employee benefit plans and other general corporate overhead functions we share with Martin Resource Management Corporation retained businesses. This allocation is based on the percentage of time spent by Martin Resource Management Corporation personnel that provide such centralized services. GAAP also permits other methods for allocation of these expenses, such as basing the allocation on the percentage of revenues contributed by a segment. The allocation of these expenses between Martin Resource Management Corporation and us is subject to a number of judgments and estimates, regardless of the method used. We can provide no assurances that our method of allocation, in the past or in the future, is or will be the most accurate or appropriate method of allocation for these expenses. Other methods could result in a higher allocation of selling, general and administrative expense to us, which would reduce our net income.

Under the Omnibus Agreement, we are required to reimburse Martin Resource Management Corporation for indirect general and administrative and corporate overhead expenses. The Conflicts Committee of our general partner approved the following reimbursement amounts during the three months ended March 31, 20202021 and 2019:2020:

2021 Senior Notes

For a description of our 7.25% senior unsecured notes due 2021, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Description of Our Long-Term Debt" in our Annual Report on Form 10-K for the year ended December 31, 2019, as amended.

Revolving Credit Facility

At March 31, 2020,2021, we maintained a $400.0$300.0 million revolving credit facility. The revolving credit facility that matures on (a) August 31, 2023, or (b) August 19, 2020 if the 2021 Notes have not been voluntarily refinanced on or prior to August 19, 2020.

2023. As of March 31, 2020,2021, we had $170.0$176.0 million outstanding under the revolving credit facility and $17.1$20.4 million of outstanding irrevocable letters of credit, leaving a maximum available to be borrowed under our credit facility for future revolving credit borrowings and letters of credit of $212.9$103.6 million. After giving effect to our then current borrowings, outstanding letters of credit to the extent drawn, and the financial covenants contained in our revolving credit facility, we had the ability to borrow approximately $46.2$29.3 million in additional amounts thereunder as of March 31, 2020.2021.
The revolving credit facility is used for ongoing working capital needs and general partnership purposes, and to finance permitted investments, acquisitions and capital expenditures.  During the three months ended March 31, 2020,2021, the level of outstanding draws on our credit facility has ranged from a low of $170.0$148.0 million to a high of $223.0$201.0 million.

The credit facility is guaranteed by substantially all of our subsidiaries. Obligations under the credit facility are secured by first priority liens on substantially all of our assets and those of the guarantors, including, without limitation, inventory, accounts receivable, bank accounts, marine vessels, equipment, fixed assets and the interests in our subsidiaries.

We may prepay all amounts outstanding under the credit facility at any time without premium or penalty (other than customary LIBOR breakage costs), subject to certain notice requirements. The credit facility requires mandatory prepayments of amounts outstanding thereunder with excess cash that exceeds $25.0 million and the net proceeds of certain asset sales, equity issuances and debt incurrences. If we sell assets and receive net cash proceeds in excess of $25.0 million, the commitments of the lenders under the revolving credit facility will be reduced by $25.0 million.

Indebtedness under the credit facility bears interest at our option at the Eurodollar Rate (the British Bankers Association(LIBOR), with a floor for LIBOR Rate)of 1%, plus an applicable margin, or the Base Rate (the highest of the Federal Funds Rate plus 0.50%, the 30-day Eurodollar Rate plus 1.0%, or the administrative agent’s prime rate) plus an applicable margin. We pay a per annum fee on all letters of credit issued under the credit facility, and we pay a commitment fee per annum on the unused revolving credit availabilitycommitments under the credit facility. The letter of credit fee, the commitment fee and the applicable margins for our interest rate vary quarterly based on our leverage ratioTotal Leverage Ratio (as defined in the credit facility, being generally computed as the ratio of total funded debt to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges) and are as follows as of March 31, 2020:2021:

At March 31, 2020, the applicable margin for revolving loans that are LIBOR loans ranges from 2.25% to 3.50% and the applicable margin for revolving loans that are base prime rate loans ranges from 1.25% to 2.50%.    The applicable margin for LIBOR borrowings at March 31, 20202021 is 3.25%.  4.00%, with a 1% floor for LIBOR.

The credit facility includes financial covenants that are tested on a quarterly basis, based on the rolling four quarter period that ends on the last day of each fiscal quarter.

In addition, the credit facility contains various covenants, which, among other things, limit our and our subsidiaries’ ability to: (i) grant or assume liens; (ii) make investments (including investments in our joint ventures) and acquisitions; (iii) enter into certain types of hedging agreements; (iv) incur or assume indebtedness; (v) sell, transfer, assign or convey assets; (vi) repurchase our equity, make distributions and certain other restricted payments, but the credit facility permits us(including a limit on our ability to make quarterly distributions to unitholders so long as no default or eventin excess of default exists under$0.005 per unit unless our Total Leverage Ratio (as defined in the credit facility;facility) is below 3.75:1:00) and certain other restricted payments; (vii) change the nature of our business; (viii) engage in transactions with affiliates; (ix) enter into certain burdensome agreements; (x) make certain amendments to the Omnibus Agreement and our material agreements; (xi) make capital expenditures; and (xii)(xi) permit our joint ventures to incur indebtedness or grant certain liens.

The credit facility contains customary events of default, including, without limitation: (i) failure to pay any principal, interest, fees, expenses or other amounts when due; (ii) failure to meet the quarterly financial covenants; (iii) failure to observe any other agreement, obligation, or covenant in the credit facility or any related loan document, subject to cure periods for certain failures; (iv) the failure of any representation or warranty to be materially true and correct when made; (v) our, or any of our subsidiaries’ default under other indebtedness that exceeds a threshold amount; (vi) bankruptcy or other insolvency events involving us or any of our subsidiaries; (vii) judgments against us or any of our subsidiaries, in excess of a threshold amount; (viii) certain ERISA events involving us or any of our subsidiaries, in excess of a threshold amount; (ix) a change in control (as defined in the credit facility); and (x) the invalidity of any of the loan documents or the failure of any of the collateral documents to create a lien on the collateral.

The credit facility also contains certain default provisions relating to Martin Resource Management Corporation. If Martin Resource Management Corporation no longer controls our general partner, the lenders under the credit facility may declare all amounts outstanding thereunder immediately due and payable. In addition, an event of default by Martin Resource Management Corporation under its credit facility could independently result in an event of default under our credit facility if it is deemed to have a material adverse effect on us.

If an event of default relating to bankruptcy or other insolvency events occurs with respect to us or any of our subsidiaries, all indebtedness under our credit facility will immediately become due and payable. If any other event of default exists under our credit facility, the lenders may terminate their commitments to lend us money, accelerate the maturity of the indebtedness outstanding under the credit facility and exercise other rights and remedies. In addition, if any event of default exists under our credit facility, the lenders may commence foreclosure or other actions against the collateral.

Senior Secured Notes due 2025 and 2024

For a description of our 11.50% senior secured second lien notes due 2025 and 10.00% senior secured 1.5 lien notes due 2024, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Description of Our Long-Term Debt" in our Annual Report on Form 10-K for the year ended December 31, 2020.

    
Capital Resources and Liquidity

Historically, we have generally satisfied our working capital requirements and funded our debt service obligations and capital expenditures with cash generated from operations and borrowings under our revolving credit facility.

AtOn March 31, 2020,2021, we had cash and cash equivalents of $0.1$1.1 million and available borrowing capacity of $46.2$103.6 million in additional amounts under our revolving credit facility with $170.0$176.0 million of borrowings outstanding.�� After giving effect to our current borrowings, outstanding letters of credit and the financial covenants contained in our revolving credit facility, we had the ability to borrow approximately $29.3 million in additional amounts thereunder as of March 31, 2021. Our revolving credit facility matures on August 31, 2023 or August 19, 2020 if our 2021 Notes have not been refinanced on or before such date. We are currently seeking to refinance the 2021 Notes, although no assurance can be given. 


Upon the successful refinancing of the 2021 Notes, weWe expect that our primary sources of liquidity to meet operating expenses, service our indebtedness, pay distributions to our unitholders and fund capital expenditures will be provided by cash flows generated by our operations, borrowings under our revolving credit facility and access to the debt and equity capital markets.  Our ability to generate cash from operations will depend upon our future operating performance, which is subject to certain risks.   For a discussion of such risks, please read "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2019,2020, filed with the SEC on February 14, 2020, as updated and supplemented in Part II, Item 1A of this Quarterly Report on Form 10-Q, as may be further updated and supplemented from time to time in our future Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.March 3, 2021.  In addition, due to the covenants in our revolving credit facility, our financial and operating performance impacts the amount we are permitted to borrow under that facility. 

To address these challenges, since July of 2018, we have taken a number of strategic actions to strengthen our balance sheet and reduce leverage, such as asset dispositions and acquisitions, reductions in the distributions payable to our unitholders and efforts to focus our growth on business segments with a stronger economic outlook. For example, in an effort to preserve liquidity, we recently reduced the quarterly cash distribution per common unit to $0.0625 beginning with the distribution payable for the fourth quarter of 2019.  We expect this distribution reduction, along with the reduction announced in 2019, to result in approximately $68.2 million in cash we can retain annually for debt reduction and investment in higher return opportunities.   

If we are unable to refinance the 2021 Notes and are unable to repay the outstanding borrowings under our revolving credit facility on August 19, 2020, we would be in default under our revolving credit facility.  An event of default under our revolving credit facility would allow the lenders to declare the balance outstanding thereunder due and payable in full, which could trigger cross-defaults under other agreements, which could also result in the acceleration of those obligations by the counterparties to those agreements.

We are in compliance with all debt covenants as of March 31, 20202021 and expect to be in compliance for the next twelve months provided the Partnership successfully completes the refinancing of the 2021 Notes.months.

Interest Rate Risk
    
We are subject to interest rate risk on our credit facility due to the variable interest rate and may enter into interest rate swaps to reduce this variable rate risk.

Seasonality

A substantial portion of our revenues is dependent on sales prices of products, particularly NGLs and fertilizers, which fluctuate in part based on winter and spring weather conditions. The demand for NGLs is strongest during the winter heating season and the refinery blending season. The demand for fertilizers is strongest during the early spring planting season. However, our Terminalling and Storage and Transportation business segments and the molten sulfur business are typically not impacted by seasonal fluctuations and a significant portion of our net income is derived from our Terminalling and Storage, Sulfur Services and Transportation business segments. Further, extraordinary weather events, such as hurricanes, have in the past, and could in the future, impact our Terminalling and Storage, Sulfur Services, and Transportation business segments.

Impact of Inflation

Inflation did not have a material impact on our results of operations for the three months ended March 31, 20202021 or 2019.2020.  Although the impact of inflation has been insignificant in recent years, it is still a factor in the U.S. economy and may increase the cost to acquire or replace property, plant and equipment. It may also increase the costs of labor and supplies.  In the future, increasing energy prices could adversely affect our results of operations. Diesel fuel, natural gas, chemicals and other supplies are recorded in operating expenses.  An increase in price of these products would increase our operating expenses which could adversely affect net income. We cannot provide assurance that we will be able to pass along increased operating expenses to our customers.

Environmental Matters

Our operations are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which these operations are conducted. We incurred no material environmental costs, liabilities or expenditures to mitigate or eliminate environmental contamination during the three months ended March 31, 2020 2021 or 2019.
2020.

Item 3.Quantitative and Qualitative Disclosures about Market Risk

Commodity Risk. The Partnership from time to time uses derivatives to manage the risk of commodity price fluctuation. Commodity risk is the adverse effect on the value of a liability or future purchase that results from a change in commodity price.  We have established a hedging policy and monitor and manage the commodity market risk associated with potential commodity risk exposure.  In addition, we focus on utilizing counterparties for these transactions whose financial condition is appropriate for the credit risk involved in each specific transaction.

We have entered into hedging transactions as of March 31, 20202021 to protect a portion of our commodity price risk exposure. These hedging arrangements are in the form of swaps and options for NGLs. We have instruments totaling a gross notional quantity of 25,000225,000 barrels settling during the month ofperiod from April 2020.30, 2021 through June 30, 2021. These instruments settle against the applicable pricing source for each grade and location. These instruments are recorded on our Consolidated and Condensed Balance Sheets at March 31, 20202021 in "Fair value of derivatives" as a current asset of $0.002$0.01 million. Based on the current net notional volume hedged as of March 31, 2020,2021, a $0.10 change in the expected settlement price of these contracts would result in an impact to our net income of approximately $0.1$0.9 million.

Interest Rate Risk. We are exposed to changes in interest rates as a result of our credit facility, which had a weighted-average interest rate of 3.93%5.00% as of March 31, 2020.2021.  Based on the amount of unhedged floating rate debt owed by us on March 31, 2020,2021, the impact of a 100 basis point increase in interest rates on this amount of debt would result in an increase in interest expense and a corresponding decrease in net income of approximately $1.7$1.8 million annually.

We are not exposed to changes in interest rates with respect to our 20212024 Notes and 2025 Notes as these obligations are fixed rate.  TheBased on the quoted prices for identical liabilities in markets that are not active at March 31, 2021, the estimated fair value of the 20212024 Notes and 2025 Notes was approximately $146.8$56.0 million as of March 31, 2020, based on market prices of similar debt at March 31, 2020.and $299.2 million respectively. Market risk is estimated as the potential decrease in fair value of our long-term debt resulting from a hypothetical increase of a 100 basis point increase in interest rates. Such an increase in interest rates at March 31, 2021, would result in approximately a $0.7$0.2 million decrease in the fair value of our long-term debt at March 31, 2020.
2024 Notes and a $9.6 million decrease in the fair value of our 2025 Notes.

Item 4.Controls and Procedures

Evaluation of disclosure controls and procedures. In accordance with Rules 13a-15 and 15d-15 of the Securities Exchange Act, of 1934, as amended (the "Exchange Act"), we, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer of our general partner, carried out an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer of our general partner concluded that our disclosure controls and procedures were effective, as of the end of the period covered by this report, to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

There were no changes in our internal controls over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II - OTHER INFORMATION

Item 1.Legal Proceedings

From time to time, we are subject to certain legal proceedings claims and disputes that arise in the ordinary course of our business. Although we cannot predict the outcomes of these legal proceedings, we do not believe these actions, in the aggregate, will have a material adverse impact on our financial position, results of operations or liquidity. Information regarding legal proceedings is set forth in Note 1413 in Part I of this Form 10-Q.

Item 1A.Risk Factors

Except as stated below, there    There have been no material changes to the Partnership's risk factors since our Annual Report on Form 10-K for the year ended December 31, 2019,2020, filed with the SEC on February 14, 2020.March 3, 2021.

The reduction in demand for refined products resulting from measures taken to prevent the spread of the COVID-19 virus has and is likely to continue to adversely affect our results of operations, cash flows and financial condition for an indeterminate amount of time.

The markets have experienced a decline in oil prices in response to oil demand concerns due to the economic impacts of the COVID-19 pandemic, greatly impacting the demand for refined products resulting in a significant reduction in refinery utilization. As demand for our services and products decline, we could experience a reduction in the utilization of our assets. The continued spread of COVID-19 or a similar pandemic could result in further instability in the markets and decreases in commodity prices resulting in further adverse impacts on our results of operations, cash flows, and financial condition. In addition, the continued spread of the COVID-19 virus, or similar pandemic, and the continuation of the measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter in place orders, and shutdowns, may further impact our workforce and operations, the operations of our customers, and those of our vendors and suppliers. There is considerable uncertainty regarding such measures and potential future measures, which would have a material adverse effect on our results of operations, cash flows, and financial condition.
