Forward-Looking Statements

This Quarterly Report on Form 10-Q includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Statements included in this quarterly report that are not historical facts (including any statements concerning plans and objectives of management for future operations or economic performance, or assumptions or forecasts related thereto), including, without limitation, the information set forth in Management’s Discussion and Analysis of Financial Condition and Results of Operations, are forward-looking statements. These statements can be identified by the use of forward-looking terminology including "forecast," "may," "believe," "will," "expect," "anticipate," "estimate," "continue," or other similar words. These statements discuss future expectations, contain projections of results of operations or of financial condition or state other "forward-looking" information. We and our representatives may from time to time make other oral or written statements that are also forward-looking statements.

These forward-looking statements are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements.

Because these forward-looking statements involve risks and uncertainties, actual results could differ materially from those expressed or implied by these forward-looking statements for a number of important reasons, including those discussed under "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2019, 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, and as may be updated and supplemented from time to time in our future Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.

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.

("MTI") as if the Partnership owned these assets for the periods presented. See below "Acquisition of Martin Transport, Inc." within this Note 1 for more information.14, 2020.

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"Natural Gas Storage Assets”Assets") to Hartree Cardinal Gas, LLC ("Hartree"), a subsidiary of Hartree Bulk Storage, LLC.

The net proceeds were used to reduce outstanding borrowings under the Partnership's revolving credit facility. The Partnership has concluded the disposition representsrepresented a strategic shift and will havewhich 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 and six months ended June 30, 2019 and 2018.March 31, 2019. See Note 43 for more information.

AcquisitionImpact of Martin Transport, Inc.COVID-19 Pandemic. On January 2,A novel strain of coronavirus (“COVID-19”) surfaced in late 2019 and has spread around the Partnership acquired allworld, including to the United States. In March 2020, the World Health Organization declared COVID-19 a pandemic. Due to the economic impacts of the issued and outstanding equity interestsCOVID-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 MTI from Martin Resource Management Corporation. MTI operates a fleetthe Organization of tank trucks providing transportation of petroleum products, liquid petroleum gas, chemicals, sulfurPetroleum Exporting Countries and other products, as well as owns 23 terminals located throughoutnon-OPEC producer nations during the Gulf Coastfirst quarter 2020 and Southeasternglobal storage considerations. Travel restrictions and stay-at-home orders implemented by governments in many regions ofand countries across the globe, including the United States.States, have greatly impacted the demand for refined products resulting in a significant reduction in refinery utilization.

The acquisition of MTI was considered a transfer of net assets between entities under common control. As a result,COVID-19 pandemic has impacted the acquisition of MTI was recorded at amounts based on the historical carrying value of these assets at January 1, 2019,Partnership's 2020 performance to date, and the Partnership is requiredexpects to update its historical financial statementscontinue to includeexperience the activitiesimpacts of MTICOVID-19 throughout the remainder of 2020 as a result of continued reduction in refined product demand across the industries the Partnership serves.

Divestiture of WTLPG Partnership Interest.On July 31, 2018,Management considered the Partnership completed the sale of its 20 percent non-operating interest in West Texas LPG Pipeline L.P. ("WTLPG") to ONEOK, Inc. (“ONEOK”). WTLPG owns an approximate 2,300 mile common-carrier pipeline system that primarily transports NGLs from New Mexico and Texas to Mont Belvieu, Texas for fractionation. A wholly-owned subsidiary of ONEOK, Inc. is the operatorimpact of the assets. The Partnership has concludedCOVID-19 pandemic on the disposition represents a strategic shiftassumptions and will have a major effect on itsestimates used in the preparation of the financial results going forward.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 has presentedrecorded 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 operations and cash flows relating to its equity method investment in WTLPGthese assessments did not have a material impact on the Partnership's results as discontinued operations for the three and six months ended June 30, 2018. See Note 4 for more information.of March 31, 2020.

NOTE 2. NEW ACCOUNTING PRONOUNCEMENTS

In June 2018,During the FASB issued ASU 2018-07, Compensation - Stock Compensation: Improvements to Non-employee Share-Based Payment Accounting, which will expandfirst quarter of 2020, the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. The standard is effective for Partnership's financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Partnership adopted thisAccounting Standards Update (“ASU”) 2016-13, "Financial Instruments - Credit Losses," which required the Partnership to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaced the existing incurred loss model and is applicable to the measurement of credit losses on financial assets, including trade receivables. Adoption of the new standard effective January 1, 2019. The result of this adoption did not have a material impact on the Partnership'sPartnership’s consolidated and condensed financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, which introduces the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. Lessor accounting under the new standard is substantially unchanged and the Partnership believes substantially all of our leases will continue to be classified as operating leases under the new standard. Additional qualitative and quantitative disclosures, including significant judgments made by management, will be required.  The update is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those reporting periods, with early adoption permitted. The original guidance required application on a modified retrospective basis with the earliest period presented. In August 2018, the FASB issued ASU 2018-11, Targeted Improvements to Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 842, which includes an option to not restate comparative periods in transition and elect to use the effective date of ASC 842, Leases, as the date of initial application of transition. The Partnership adopted this ASU on January 1, 2019, electing the transition option provided under ASU 2018-11. Consequently, financial information was not updated and the disclosures required under the new standard are not provided for dates and periods before January 1, 2019.

The new standard provides a number of optional practical expedients in transition. The Partnership elected the "package of practical expedients", which permits the Partnership not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The new standard also provides practical expedients for an entity’s ongoing accounting. The Partnership elected the short-term lease recognition exemption for all leases that qualify. This means, for those assets that qualify, the Partnership did not recognize Right-of-Use ("ROU") assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. See Note 9 for more information.

NOTE 3. ACQUISITIONS

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.

NOTE 7. INVESTMENT IN WEST TEXAS LPG PIPELINE L.P.

As discussed in Note 4, on July 31, 2018, the Partnership completed the sale of its 20% non-operating interest in WTLPG. Prior to the sale, the Partnership owned a 19.8% limited partnership and 0.2% general partnership interest in WTLPG. A wholly-owned subsidiary of ONEOK is the operator of the assets.

The Partnership is permitted to make quarterly distributions so long as no event of default exists.

2 The Partnership is in compliance with all debt covenants as of June 30, 2019March 31, 2020 and December 31, 2018,2019, respectively.

4 On July 18, 2019,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 amendedis 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 amongmeet 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 things, extendagreements, which could also result in the maturity dateacceleration 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, to August 2023 and reduce commitments from $500,000 to $400,000.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 $7,330$16,736 and $6,077$19,363 for the three months ended June 30,March 31, 2020 and 2019, and 2018, respectively.  The Partnership paid cash interest, net of capitalized interest, in the amount of $26,693 and $24,955 for the six months ended June 30, 2019 and 2018, respectively.  Capitalized interest was $0$4 and $167$2 for the three months ended June 30,March 31, 2020 and 2019, and 2018, respectively. Capitalized interest was $2 and $328 for the six months ended June 30, 2019 and 2018, respectively.

NOTE 9.7. LEASES

In February 2016, the FASB issued ASU 2016-02, Leases, which introduces the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. In August 2018, the FASB issued ASU 2018-11, Targeted Improvements to ASC 842, which includes an option to not restate comparative periods in transition and elect to use the effective date of ASC 842, Leases, as the date of initial application of transition. The Partnership elected the effective date transition method in ASC 842 and adopted the standard beginning January 1, 2019.

The new standard provides a number of optional practical expedients in transition. The Partnership elected the "package of practical expedients", which permits the Partnership not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The Partnership also elected the short-term lease recognition exemption, meaning the Partnership does not recognize ROU assets or lease liabilities for all leases that qualify. Lease agreements with lease and non-lease components are combined as a single lease component. Variable lease payments are generally expensed as incurred and include certain index-based changes in rent, certain non-lease components, such as maintenance and other services provided by the lessor, and other charges included in the lease. 

The adoption of this standard resulted in the recording of approximately $19,047 of additional assets and liabilities on its Consolidated Balance Sheet as of January 1, 2019. The Partnership also acquired certain operating leases in the MTI transaction that resulted in additional assets and liabilities being recorded at the transaction date in accordance with ASU 2016-02 in the amount of $6,505.
    
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 17 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 11.9. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Partnership’s revenues and cost of products sold are materially impacted by changes in NGL prices. Additionally, the Partnership's results of operations are materially impacted by changes in 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 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 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 June 30, 2019March 31, 2020 to protect a portion of its commodity price risk exposure. These hedging arrangements are in the form of swaps for NGLs. At June 30, 2019,March 31, 2020, the Partnership has instruments totaling a gross notional quantity of 370,00025,000 barrels settling during the period from July 1, 2019 through September 30, 2019.month of April 2020. At December 31, 2018,2019, the Partnership had instruments totaling a gross notional quantity of 55,000452,000 barrels settling during the period from January 31, 20192020 through February 28, 2019.29, 2020. 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.

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.

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 no0 incentive distributions during the sixthree months ended June 30, 2019March 31, 2020 and 2018.2019.
 
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:

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.

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 June 30, 2019,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.

NOTE 16.14. COMMITTMENTS 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 has 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 17.15. 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 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.

Assets and liabilities measured at fair value on a recurring basis are summarized below:

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 noncurrent 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 senior unsecured notes2021 Notes is considered Level 1, as the fair value is based on quoted market prices in active markets.

The operations of a partnership are generally not subject to income taxes, except for Texas margin tax, because its income is taxed directly to its partners. MTI is subject to income taxes due to its corporate structure. Total income tax expense of $429 and $877,$347, related to the operation of the subsidiary, for the three and six months ended June 30, 2019, respectively,March 31, 2020, resulted in an effective income tax rate of 26.30% and 25.49%, respectively.32.17%.

Total income tax expense (benefit) of $0 and $0,$448, related to the operation of the subsidiary, for the three and six months ended June 30, 2018, respectively,March 31, 2019, resulted in an effective income tax rate of 0% and 0%, respectively.24.79%. The increase in the effective income tax rate for income taxes during the three months ended March 31, 2020, compared to the three months ended March 31, 2019, is primarily due to an increase in permanent differences and a decrease in income before income taxes. The decrease in the provision for income taxes during the three and six months ended June 30, 2019,March 31, 2020, compared to the three and six months ended June 30, 2018, issimilar period in 2019, was primarily due to the impact of a changedecrease in MTI’sincome 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 statusprovisions 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 non-taxable Qualified Subchapter S subsidiary (“QSub”("QSub") to a taxable C Corporation upon acquisition.

Prior to the acquisition, MTI was a QSub of Martin Resource Management Corporation, a qualifying S Corporation. A QSub is not treated as a separate corporation for federal income tax purposes as it is deemed liquidated intoprecluded from carrying back net operating losses to its S Corporation parent. S Corporations are generally not subject to incomeQSub taxable years. The other applicable provisions of the CARES Act have no material impact on the annual effective tax rate ("AETR"), deferred taxes, because income and losses flow through to shareholders and are reported on their individual returns. Subsequent to the acquisition, MTI will file stand-alone C Corporation returns.

A current federal income tax expense (benefit) of $(78)$133 and $218,$297, related to the operation of the subsidiary, were recorded for the three and six months ended June 30,March 31, 2020 and 2019, and $0 and $0 for the three and six months ended June 30, 2018, respectively. A current state income tax expense (benefit) of $20$(72) and $(198)$(218), related to the operation of the subsidiary, were recorded for the three and six months ended June 30,March 31, 2020 and 2019, and $0 and $0 for the three and six months ended June 30, 2018, respectively. In connection with the MTI acquisition, the Partnership also established deferred income taxes of $24,781 associated with book and tax basis differences of the acquired assets and liabilities. The basis differences are primarily related to property, plant and equipment and deductible tax goodwill. Equity of MTI was adjusted for the deferred tax consequences of the basis differences caused by the transaction between entities under common control.respectively

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 $487$286 and $856$369 was recorded for the three and six months ended June 30,March 31, 2020 and 2019, respectively, and $0 and $0 was recorded for the three and six months ended June 30, 2018, respectively. A deferred tax asset of $23,925$23,136 and $0,$23,422, related to the cumulative book and tax temporary differences, existed at June 30, 2019March 31, 2020 and December 31, 2018,2019, 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.

Forward-Looking Statements

This quarterly report on Form 10-Q includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Statements included in this quarterly report that are not historical facts (including any statements concerning plans and objectives of management for future operations or economic performance, or assumptions or forecasts related thereto), including, without limitation, the information set forth in Management’s Discussion and Analysis of Financial Condition and Results of Operations, are forward-looking statements. These statements can be identified by the use of forward-looking terminology including "forecast," "may," "believe," "will," "expect," "anticipate," "estimate," "continue," or other similar words. These statements discuss future expectations, contain projections of results of operations or of financial condition or state other "forward-looking" information. We and our representatives may from time to time make other oral or written statements that are also forward-looking statements.

These forward-looking statements are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements.

Because these forward-looking statements involve risks and uncertainties, actual results could differ materially from those expressed or implied by these forward-looking statements for a number of important reasons, including those discussed under "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission (the "SEC") on February 19, 2019 and in this report.

Overview
 
We are a publicly traded limited partnership with a diverse set of operations focused primarily in the United States ("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

Natural gas liquidsNGL 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, fertilizer manufacturers 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 June 30, 2019,March 31, 2020, Martin Resource Management Corporation owned 15.7% 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") 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 natural gas liquidsNGL 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 and our land transportation business in the early 1980s. It entered into our fertilizer and terminalling and storage businesses in the early 1990s. In recent years, Martin Resource Management Corporation has increased the size of our asset base through expansions and strategic acquisitions.

Significant Recent Developments

COVID-19 Pandemic

The Partnership prioritizes the health and safety of our employees, the businesses we serve, and the communities where we live and work. To support the safety of all of our employees and operations, precautionary measures have been implemented 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 one time, monitoring the health of all employees, and implementing work-from-home initiatives for all eligible employees.

Further, we began awareness training for all of our drivers, vessel crews, blending operators and other affected personnel regarding preventative measures in or around our docks, vessels, and trucks and locations to which they are delivering. Our communication lines are open 24/7 for 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 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 our 2020 performance to date. The impact of this outbreak started 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.

DivestitureWe expect to continue to experience the adverse impacts of COVID-19 on our business throughout the remainder of 2020 as a result of an expected continued reduction in refined product demand across the industries we serve. As we look forward in our Terminalling and Storage 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, reduced 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 Storage Assets. 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.

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, the full impact of COVID-19 will not be reflected in our results of operations and overall financial performance until future periods. In an effort to conserve capital in the near-term, we are actively considering, planning and executing expense reduction initiatives and have elected to defer certain maintenance and growth capital expenditures until 2021.

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 our results as of March 31, 2020.

Other Recent Developments

Beginning 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 June 28,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 membership interests in Arcadia Gas Storage, LLC, Cadeville Gas Storage LLC, Monroe Gas Storage Company, LLCnatural gas storage assets for $215.0 million, which was an important piece of the Partnership’s strategy to strengthen the balance sheet 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 ofre-focus our operational expertise on the refinery services industry. On August 12, 2019, we completed the sale of the Natural Gas Storage Assets, we received cash proceeds of $210.1 million after transaction fees and expenses, subject to final post closing adjustments. The proceeds were used to reduce outstanding borrowings under our revolving credit facility.East Texas Pipeline for $17.5 million.

Martin Transport Inc. Stock Purchase Agreement. On October 22, 2018,
As a result of dispositions, offset by acquisitions, we entered intowere able to pay down $300.5 million of outstanding debt while incurring only a stock purchase agreement (the “Stock Purchase Agreement”)slight reduction to projected EBITDA. Consistent with Martin Resource Management Corporation to acquire allour strategy of the issuedreducing leverage and outstanding equity interests of Martin Transport, Inc. (“MTI”), a wholly-owned subsidiary of Martin Resource Management Corporation which operates a fleet of tank trucks providing transportation of petroleum products, liquid petroleum gas, chemicals, sulfur and other products, as well as owns twenty-three terminals located throughout the Gulf Coast and Southeastern regions of the United States for total consideration of $135.0 million with a $10.0 million earn-out based on certain performance thresholds. Additionally, a post-closing working capital adjustment was finalizedimproving liquidity, on January 28, 2019 which included additional consideration paid2020, we announced a $0.75 per unit reduction of our cash distribution on an annual basis, allowing us to Martin Resource Management Corporation of $2.8 million. The Stock Purchase Agreement contained customary representations and warranties. Martin Resource Management Corporation has owned and operated MTI or its predecessor for over 40 years and MTI is integralretain $29.2 million to continue to strengthen our routine movements of sulfur and NGL’s. Based on operational estimates and current transportation market conditions, this drop-down from our general partner will provide strategic long-term growth for the Partnership. This transaction closed January 2, 2019 and was effective as of January 1, 2019. As of January 1, 2019, Martin Resource Management Corporation will no longer provide land transportation services.                     balance sheet.

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. 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. 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 provide 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.

Distributable Cash Flow. 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 expect 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.

EBITDA, adjusted EBITDA and distributable 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.

Non-GAAP Financial Measures

The following table reconciles the non-GAAP financial measurements used by management to our most directly comparable GAAP measures for the three and sixthree months ended June 30,March 31, 20192020 and 20182019.

Results of Operations

The results of operations for the three and sixthree months ended June 30, 2019March 31, 2020 and 20182019 have been derived from our consolidated and condensed financial statements.


We evaluate segment performance on the basis of operating income, which is derived by subtracting cost of products sold, operating expenses, selling, general and administrative expenses, and depreciation and amortization expense from revenues.  The following table sets forth our operating revenues and operating income by segment for the three and sixthree months ended June 30, 2019March 31, 2020 and 20182019.  The results of operations for these interim periods are not necessarily indicative of the results of operations which might be expected for the entire year.


Our consolidated and condensed results of operations are presented on a comparative basis below.  There are certain items of income and expense which we do not allocate on a segment basis.  These items, including equity in earnings (loss) of unconsolidated entities, interest expense and indirect selling, general and administrative expenses, are discussed following the comparative discussion of our results within each segment.

Indirect selling, general and administrative expenses increaseddecreased for the three months ended June 30, 2019March 31, 2020 compared to the three months ended June 30, 2018March 31, 2019 primarily due to increased unit based compensation expense of $0.2 million. Indirect selling, general and administrative expenses increased for the six months ended June 30, 2019 compared to the six months ended June 30, 2018 primarily due to increased unit based compensation expense of $0.2 million and transaction expenses incurred in the first quarter of $0.2 million2019 related to the acquisition of MTI.

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 sixthree months ended June 30, 2019March 31, 2020 and 2018:2019:

Liquidity and Capital Resources
 
General

Our primary sources of liquidity to meet operating expenses, service our indebtedness, pay distributions to our unitholders and fund capital expenditures have historically been cash flows generated by our operations, borrowings under our revolving credit facility and access to debt and equity capital markets, both public and private. Management believes that expenditures forSet forth below is a description of our current capital projects will be funded with cash flows from operations, current cash balances and our current borrowing capacity under the revolving credit facility.

Recent Debt Financing Activity

Credit Facility Amendment and Extension. On July 18, 2019, the Partnership amended its revolving credit facility to, among other things, extend the maturity date from March 2020 to August 2023 and reduce commitments from $500.0 million to $400.0 million.

We believe that cash generated from operations and our borrowing capacity under our credit facility will be sufficient to meet our working capital requirements and anticipated maintenance capital expenditures in 2019. Finally, our ability to satisfy our working capital requirements, to fund planned capital expenditures and to satisfy our debt service obligations will also depend upon our future operating performance, which is subject to certain risks. Please read "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2018, for the year ended December 31, 2018, filed with the Securities and Exchange Commission (the "SEC") on February 19, 2019, for a discussion of such risks.periods indicated.

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 to make quarterly distributions to unitholders so long as no default or event of default exists under the credit facility; (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) 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.
 
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.

At March 31, 2020, we had cash and cash equivalents of $0.1 million and available borrowing capacity of $46.2 million in additional amounts under our revolving credit facility with $170.0 million of borrowings outstanding.  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, we 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, 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.  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, 2020 and expect to be in compliance for the next twelve months provided the Partnership successfully completes the refinancing of the 2021 Notes.

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.

We are in compliance with all debt covenants as of June 30, 2019 and expect to be in compliance for the next twelve months.

Seasonality

A substantial portion of our revenues areis 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 terminallingTerminalling and storageStorage and transportationTransportation 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 terminallingTerminalling and storage, sulfurStorage, Sulfur Services and transportation businesses.Transportation business segments. Further, extraordinary weather events, such as hurricanes, have in the past, and could in the future, impact our Terminalling and Storage and Transportation business segments.

Impact of Inflation

Inflation did not have a material impact on our results of operations for the sixthree months ended June 30, 2019March 31, 2020 or 2018.2019.  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 sixthree months ended June 30,March 31, 20192020 or 2018.2019.


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 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 June 30, 2019March 31, 2020 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 370,00025,000 barrels settling during the period from July 1, 2019 through September 30, 2019.month of April 2020. 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 June 30, 2019March 31, 2020 in "Fair value of derivatives" as a current liabilityasset of $2.1$0.002 million. Based on the current net notional volume hedged as of June 30, 2019,March 31, 2020, a $0.10 change in the expected settlement price of these contracts would result in an impact to our net income of approximately $1.6$0.1 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 5.65%3.93% as of June 30, 2019.March 31, 2020.  Based on the amount of unhedged floating rate debt owed by us on June 30, 2019,March 31, 2020, 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 $2.3$1.7 million annually.

We are not exposed to changes in interest rates with respect to our senior unsecured notes2021 Notes as these obligations are fixed rate.  The estimated fair value of the senior unsecured notes2021 Notes was approximately $371.5$146.8 million as of June 30, 2019,March 31, 2020, based on market prices of similar debt at June 30, 2019.March 31, 2020. 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 would result in approximately a $2.2$0.7 million decrease in the fair value of our long-term debt at June 30, 2019.March 31, 2020.


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 1614 in Part I of this Form 10-Q.

Item 1A.Risk Factors

ThereExcept as stated below, there have been no material changes to the Partnership's risk factors disclosed insince our annual reportAnnual Report on Form 10-K for the year ended December 31, 2018,2019, filed with the Securities and Exchange Commission (the "SEC")SEC on February 19, 2019.14, 2020.

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.
