Overview
We are a publicly traded limited partnership with a diverse set of operations focused primarily in theU.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 theU.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 byMartin 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 ofDecember 31, 2019 ,Martin Resource Management Corporation owned 15.7% of our total outstanding common limited partner units. Furthermore,Martin Resource Management Corporation controls MMGP, our general partner, by virtue of its 51% voting interest in 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. Our Omnibus Agreement withMartin Resource Management Corporation 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 byMartin Resource Management Corporation and our use of certain ofMartin Resource Management Corporation's trade names and trademarks. Under the terms of the Omnibus Agreement, the employees ofMartin 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. 45
--------------------------------------------------------------------------------
Beginning in 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 inWest Texas LPG Pipeline Limited Partnership for$195.0 million and the sale of a non-strategic terminal asset located inNevada for$8.0 million . OnJanuary 1, 2019 , we completed the next initiative with the acquisition ofMartin Transport, Inc. fromMartin Resource Management Corporation for$135.0 million , positioning us for cash flow growth. OnJuly 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. OnAugust 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. Consistent with our strategy of reducing leverage and improving liquidity, onJanuary 28, 2020 , we announced a$0.75 per unit reduction of our cash distribution on an annual basis, allowing us to retain$29.2 million to continue to strengthen our balance sheet.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations are based on the historical consolidated financial statements included elsewhere herein. We prepared these financial statements in conformity withUnited States generally accepted accounting principles ("U.S. GAAP" or "GAAP"). The preparation of these financial statements required us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We based our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. We routinely evaluate these estimates, utilizing historical experience, consultation with experts and other methods we consider reasonable in the particular circumstances. Our results may differ from these estimates, and any effects on our business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. Changes in these estimates could materially affect our financial position, results of operations or cash flows. You should also read Note 2, "Significant Accounting Policies" in Notes to Consolidated Financial Statements. The following table evaluates the potential impact of estimates utilized during the periods endedDecember 31, 2019 and 2018: Effect if Actual Results Judgments and Differ from Estimates and Description Uncertainties Assumptions Impairment of Long-Lived Assets We periodically evaluate Our impairment analyses Applying this impairment whether the carrying require management to use review methodology, no value of long-lived judgment in estimating impairment of long-lived assets has been impaired future cash flows and assets was recorded during when circumstances useful lives, as well as the years ended December indicate the carrying assessing the probability 31, 2019 or 2018.

How We Evaluate Our Operations
Our management uses a variety of financial and operational measurements other than our financial statements prepared in accordance withU.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 historic 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 withU.S. GAAP. Our method of computing these measures may not be the same method used to compute similar measures reported by other entities.

Indirect selling, general and administrative expenses remained consistent from 2018 to 2019. The increase in indirect selling, general and administrative expenses from 2017 to 2018 is primarily a result of increased unit based compensation expense.
Martin Resource Management Corporation allocates to us a portion of its indirect selling, general and administrative expenses for services such as accounting, treasury, clerical, engineering, legal, billing, information technology, administration of insurance, general office expenses and employee benefit plans and other general corporate overhead functions we share withMartin Resource Management Corporation retained businesses. This allocation is based on the percentage of time spent byMartin 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 betweenMartin 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 reimburseMartin Resource Management Corporation for indirect general and administrative and corporate overhead expenses. The Conflicts Committee approved the following reimbursement amounts: Year Ended December 31, Percent Year Ended December 31, Percent 2019 2018 Variance Change 2018 2017 Variance Change (In thousands) (In thousands) Conflicts Committee approved reimbursement amount$ 16,657 $ 16,416 $ 241 1%$ 16,416 $ 16,416 $ - -%

The credit facility requires mandatory prepayments of amounts outstanding thereunder with the net proceeds of certain asset sales, equity issuances and debt incurrences.

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 toMartin Resource Management Corporation . IfMartin 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 byMartin 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. 62 -------------------------------------------------------------------------------- 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. AtDecember 31, 2019 , we had cash and cash equivalents of$2.8 million and available borrowing capacity of$51.5 million in additional amounts under our revolving credit facility with$201.0 million of borrowings outstanding. Our revolving credit facility matures onAugust 31, 2023 unless our 2021 Notes have not been refinanced on or beforeAugust 19, 2020 . We are currently seeking to refinance the 2021 Notes, although no assurance can be given that we will be able to refinance the 2021 Notes. 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. Please read "Item 1A. Risk Factors - Risks related to Our Business" for a discussion of such risks. 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, over the last 18 months, 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 onAugust 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.
The Partnership is in compliance with all debt covenants as of
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 andStorage 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 andStorage and Transportation business segments. 63 --------------------------------------------------------------------------------
Impact of Inflation
Inflation did not have a material impact on our results of operations in 2019, 2018 or 2017. Although the impact of inflation has been insignificant in recent years, it is still a factor in theU.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 2019, 2018 or 2017. 64
