NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS

(Dollars in thousands, except where otherwise indicated)

March 31, 2019

(Unaudited)

NOTE 1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION

Martin Midstream Partners L.P. (the "Partnership") is a publicly traded limited partnership with a diverse set of operations focused primarily in the United States ("U.S.") Gulf Coast region. Its four primary business lines include: natural gas services, including liquids transportation and distribution services and natural gas storage; terminalling and storage services for petroleum products and by-products including the refining of naphthenic crude oil, blending and packaging of finished lubricants; sulfur and sulfur-based products processing, manufacturing, marketing and distribution; and transportation services for petroleum products and by-products.

The Partnership’s unaudited consolidated and condensed financial statements have been prepared in accordance with the requirements of Form 10-Q and U.S. Generally Accepted Accounting Principles ("U.S. GAAP") for interim financial reporting. Accordingly, these financial statements have been condensed and do not include all of the information and footnotes required by U.S. GAAP for annual audited financial statements of the type contained in the Partnership’s annual reports on Form 10-K. In the opinion of the management of the Partnership’s general partner, all adjustments and elimination of significant intercompany balances necessary for a fair presentation of the Partnership’s financial position, results of operations, and cash flows for the periods shown have been made. All such adjustments are of a normal recurring nature. Results for such interim periods are not necessarily indicative of the results of operations for the full year. These financial statements should be read in conjunction with the Partnership’s audited consolidated financial statements and notes thereto included in the Partnership’s annual report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission (the "SEC") on February 19, 2019.

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.

Correction of Immaterial Error. The first quarter amounts for 2018 have been revised to reflect a reclassification in the presentation of certain expenses associated with the manufacturing and shipping of product related to a location in the Partnership's Terminalling and Storage operating segment. The reclassification resulted in an increase in operating expenses and a decrease in cost of products sold in the amount of $1,547 for the three months ended March 31, 2018.

Acquisition of Martin Transport, Inc. On January 2, 2019, the Partnership acquired all of the issued and outstanding equity of Martin Transport, Inc. (“MTI”) from Martin Resource Management Corporation. MTI operates a fleet of tank trucks providing transportation of petroleum products, liquid petroleum gas, chemicals, sulfur and other products, as well as owns 23 terminals located throughout the Gulf Coast and Southeastern regions of the United States.

The acquisition of MTI was considered a transfer of net assets between entities under common control. As a result, the acquisition of MTI was recorded at amounts based on the historical carrying value of these assets at January 1, 2019, and the Partnership is required to update its historical financial statements to include the activities of MTI as of the date of common control. See Note 3 for more information. The Partnership’s accompanying historical financial statements have been retrospectively updated to reflect the effects on financial position, cash flows and results of operations attributable to the activities of MTI as if the Partnership owned these assets for the periods presented. See Note 3 for separate results of MTI for the three months ended March 31, 2018. Net income attributable to MTI for periods prior to the Partnership’s acquisition of the assets is not allocated to the limited partners for purposes of calculating net income per limited partner unit. See Note 12.

Divestiture of WTLPG Partnership Interest. On July 31, 2018, 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 operator of the assets. The Partnership has concluded the disposition represents a strategic shift and will have a major effect on its financial results going forward. As a result, the Partnership has presented the results of operations and cash flows relating to its equity method investment in WTLPG as discontinued operations for the three months ended March 31, 2018. See Note 4 for more information.

NOTE 2. NEW ACCOUNTING PRONOUNCEMENTS

In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation: Improvements to Non-employee Share-Based Payment Accounting, which will expand 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 this

MARTIN MIDSTREAM PARTNERS L.P.

NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS

(Dollars in thousands, except where otherwise indicated)

March 31, 2019

(Unaudited)

standard effective January 1, 2019. The result of this adoption did not have a material impact on the Partnership'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. Leases" for more information.

NOTE 3. ACQUISITIONS

Martin Transport Inc. Stock Purchase Agreement. On January 2, 2019, the Partnership acquired all of the issued and outstanding equity of 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 23 terminals located throughout the Gulf Coast and Southeastern regions of the United States for total consideration as follows:



Purchase price¹	$	135,000
Plus: Working Capital Adjustment	2,795
Less: Finance lease obligations assumed	(11,682		)
Cash consideration paid	$	126,113

¹The stock purchase agreement also includes a $10,000 earn-out based on certain performance thresholds.

The transaction closed on January 2, 2019 and was effective as of January 1, 2019 and was funded with borrowings under the Partnership's revolving credit facility.

NOTE 4. DIVESTITURES AND DISCONTINUED OPERATIONS

Discontinued Operations

Divestiture of WTLPG Partnership Interest. On July 31, 2018, the Partnership completed the sale of its 20 percent non-operating interest in WTLPG to 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 operator of the assets. In consideration for the sale of these assets, the Partnership received cash proceeds of $193,705, after transaction fees and expenses. The proceeds from the sale were used to reduce outstanding borrowings under the Partnership's revolving credit facility. The Partnership has concluded the disposition represents a strategic shift and will have a major effect on its financial results going forward. As a result, the Partnership has presented the results of operations and cash flows relating to its equity method investment in WTLPG as discontinued operations for the three months ended March 31, 2018.

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

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

Terminalling and Storage Segment

Revenue is recognized for storage contracts based on the contracted monthly tank fixed fee. For throughput contracts, revenue is recognized based on the volume moved through the Partnership’s terminals at the contracted rate. For the Partnership’s tolling agreement, revenue is recognized based on the contracted monthly reservation fee and throughput volumes moved through the facility. When lubricants and drilling fluids are sold by truck or rail, revenue is recognized when title is transfered, which is either upon delivering product to the customer or when the product leaves the Partnership's facility, depending on the specific terms of the contract. Delivery of product is invoiced as the transaction occurs and is generally paid within a month.

Natural Gas Services Segment

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

MARTIN MIDSTREAM PARTNERS L.P.

March 31, 2019

(Unaudited)

service is provided to the customer. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

Sulfur Services Segment

Revenue from sulfur product sales is recognized when the customer takes title to the product. Delivery of product is invoiced as the transaction occurs and are generally paid within a month. Revenue from sulfur services is recognized as services are performed during each monthly period. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

Transportation Segment

Revenue related to land transportation is recognized for line hauls based on a mileage rate. For contracted trips, revenue is recognized upon completion of the particular trip. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

Revenue related to marine transportation is recognized for time charters based on a per day rate. For contracted trips, revenue is recognized upon completion of the particular trip. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

The table includes estimated minimum revenue expected to be recognized in the future related to performance obligations that are unsatisfied at the end of the reporting period. The Partnership applies the practical expedient in ASC 606-10-50-14(a) and does not disclose information about remaining performance obligations that have original expected durations of one year or less.

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 West Texas LPG Pipeline L.P. ("WTLPG"). A wholly-owned subsidiary of ONEOK, Inc. is the operator of the assets. 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. The Partnership recognized its 20% interest in WTLPG as "Investment in WTLPG" on its Consolidated and Condensed Balance Sheets. The Partnership accounted for its ownership interest in WTLPG under the equity method of accounting. As discussed in Note 4, the Partnership sold its 20% non-operating partnership interest to ONEOK on July 31, 2018.

Selected financial information for WTLPG during the period of ownership is as follows:

NOTE 8. LONG-TERM DEBT

At March 31, 2019 and December 31, 2018, long-term debt consisted of the following:



	March 31, 2019			December 31, 2018
$664,444 Revolving credit facility at variable interest rate (5.49%¹ weighted average at March 31, 2019), due March 2020 secured by substantially all of the Partnership’s assets, including, without limitation, inventory, accounts receivable, vessels, equipment, fixed assets and the interests in the Partnership’s operating subsidiaries and equity method investees, net of unamortized debt issuance costs of $2,890 and $3,537, respectively^2,4	$	401,110		$	283,463

Less: current portion	(401,110		)	—
Total long-term debt, net of current portion	$	373,090		$	656,459

¹ Interest rate fluctuates based on the LIBOR rate plus an applicable margin set on the date of each advance. The margin above LIBOR is set every three months. Indebtedness under the credit facility bears interest at LIBOR plus an applicable margin or the base prime rate plus an applicable margin. All amounts outstanding at March 31, 2019 and December 31, 2018 were at LIBOR plus an applicable margin. The applicable margin for revolving loans that are LIBOR loans ranges from 2.00% to 3.00% and the applicable margin for revolving loans that are base prime rate loans ranges from 1.00% to 2.00%. The applicable margin for existing LIBOR borrowings at March 31, 2019 is 3.00%. The credit facility contains various covenants which limit the Partnership’s ability to make certain investments and acquisitions; enter into certain agreements; incur indebtedness; sell assets; and make certain amendments to the Partnership's omnibus agreement with Martin Resource Management Corporation (the "Omnibus Agreement"). 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 March 31, 2019 and December 31, 2018, respectively.

³The 2021 indenture restricts the Partnership’s ability to sell assets; pay distributions or repurchase units or redeem or repurchase subordinated debt; make investments; incur or guarantee additional indebtedness or issue preferred units; and consolidate, merge or transfer all or substantially all of its assets.

⁴On April 16, 2019, the Partnership amended its revolving credit facility to, among other things, reduce commitments from $664,444 to $500,000 and to adjust the permitted Leverage Ratio (as defined in the credit agreement) to 5.85 times for the fiscal quarters ended March 31, 2019 and June 30, 2019.

As of March 31, 2019, the Partnership’s revolving credit facility was due within twelve months and has therefore been presented as a current liability on the Partnership’s March 31, 2019 consolidated and condensed balance sheets. The Partnership intends to extend the maturity of the credit facility and had previously determined to delay the extension until after finalization of the marketing and sales process related to the sale of its natural gas storage assets, which if consummated would allow the impact of the receipt of the proceeds to give effect to the amended commitment amount and the extended maturity date.

The Partnership paid cash interest, net of capitalized interest, in the amount of $19,363 and $18,878 for the three months ended March 31, 2019 and 2018, respectively. Capitalized interest was $2 and $161 for the three months ended March 31, 2019 and 2018, respectively.

NOTE 9. 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.

Our leases have remaining lease terms of 1 year to 18 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.

The Partnership's future minimum lease obligations as of December 31, 2018 consisted of the following:

NOTE 11. 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 has established a hedging policy and monitors and manages the commodity market risk associated with potential commodity risk exposure. In addition, the Partnership has focused on utilizing counterparties for these transactions whose financial condition is appropriate for the credit risk involved in each specific transaction. The Partnership has entered into hedging transactions as of March 31, 2019 to protect a portion of its commodity price risk exposure. These hedging arrangements are in the form of swaps for NGLs. The Partnership has instruments totaling a gross notional quantity of 472,000 barrels settling during the period from April 1, 2019 through September 30, 2019. At December 31, 2018, the Partnership had instruments totaling a gross notional quantity of 55,000 barrels settling during the period from January 31, 2019 through February 28, 2019. These instruments settle against the applicable pricing source for each grade and location.

(b) Interest Rate Derivative Instruments

The Partnership is exposed to market risks associated with interest rates. Market risk is the adverse effect on the value of a financial instrument that results from a change in interest rates. We minimize this market risk by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken. From time to time, the Partnership enters into interest rate swaps to manage interest rate risk associated with the Partnership’s variable rate credit facility and its fixed rate senior unsecured notes. At March 31, 2019 and 2018, the Partnership did not have any outstanding interest rate derivative instruments.

For information regarding gains and losses on interest rate derivative instruments, see "Tabular Presentation of Gains and Losses on Derivative Instruments" below.

The following table summarizes the fair value and classification of the Partnership’s derivative instruments in its Consolidated and Condensed Balance Sheets:

NOTE 12. PARTNERS' CAPITAL

As of March 31, 2019, Partners’ capital consisted of 38,899,590 common limited partner units, representing a 98% partnership interest, and a 2% general partner interest. Martin Resource Management Corporation, through subsidiaries, owns 6,114,532 of the Partnership's common limited partner units representing approximately 15.7% of the Partnership's outstanding common limited partner units. Martin Midstream GP LLC ("MMGP"), the Partnership's general partner, owns the 2% general partnership interest. Martin Resource Management Corporation controls the Partnership's general partner, by virtue of its 51% voting interest in MMGP Holdings, LLC ("Holdings"), the sole member of the Partnership's general partner.

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

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 no incentive distributions during the three months ended March 31, 2019 and 2018.

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:

	Three Months Ended March 31,
	2019	2018
Basic weighted average limited partner units outstanding	38,681,925	38,621,375
Dilutive effect of restricted units issued	—	8,252
Total weighted average limited partner diluted units outstanding	38,681,925	38,629,627

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

NOTE 13. UNIT BASED AWARDS

The Partnership recognizes compensation cost related to unit-based awards to both employees and non-employees in its consolidated and condensed financial statements in accordance with certain provisions of ASC 718. Amounts recognized in selling, general, and administrative expense in the consolidated and condensed financial statements with respect to these plans are as follows:



	Three Months Ended March 31,
	2019		2018
Employees	$	329	$	96
Non-employee directors	23		36
Total unit-based compensation expense	$	352	$	132

All of the Partnership's outstanding awards at March 31, 2019 met the criteria to be treated under equity classification.

Long-Term Incentive Plans

The Partnership's general partner has a long-term incentive plan for employees and directors of the general partner and its affiliates who perform services for the Partnership.

On May 26, 2017, the unitholders of the Partnership approved the Martin Midstream Partners L.P. 2017 Restricted Unit Plan (the "2017 LTIP"). The plan currently permits the grant of awards covering an aggregate of 3,000,000 common units, all of which can be awarded in the form of restricted units. The plan is administered by the compensation committee of the general partner’s board of directors (the "Compensation Committee").

A restricted unit is a unit that is granted to grantees with certain vesting restrictions, which may be time-based and/or performance-based. Once these restrictions lapse, the grantee is entitled to full ownership of the unit without restrictions. The Compensation Committee may determine to make grants under the plan containing such terms as the Compensation Committee shall determine under the plan. With respect to time-based restricted units ("TBRU's"), the Compensation Committee will determine the time period over which restricted units granted to employees and directors will vest. The Compensation Committee may also award a percentage of restricted units with vesting requirements based upon the achievement of specified pre-established performance targets ("Performance Based Restricted Units" or "PBRU's"). The performance targets may include, but are not limited to, the following: revenue and income measures, cash flow measures, net income before interest expense and income tax expense ("EBIT"), net income before interest expense, income tax expense, and depreciation and amortization ("EBITDA"), distribution coverage metrics, expense measures, liquidity measures, market measures, corporate sustainability metrics, and other measures related to acquisitions, dispositions, operational objectives and succession planning objectives. PBRU's are earned only upon our achievement of an objective performance measure for the performance period. PBRU's which vest are payable in common units. Unvested units granted under the 2017 LTIP may or may not participate in cash distributions depending on the terms of each individual award agreement.

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

On February 11, 2019, the Partnership issued 5,648 TBRU's to each of the Partnership's three independent directors under the 2017 LTIP. These restricted common units vest in equal installments of 1,412 units on January 24, 2020, 2021, 2022, and 2023.

On March 1, 2018, the Partnership issued 301,550 TBRU's and 317,925 PBRU's to certain employees of Martin Resource Management Corporation. The TBRU's vest in equal installments over a three-year service period. The PBRU's will vest at the conclusion of a three-year performance period based on certain performance targets. In addition, the PBRU's awarded on March 1, 2018 that are achieved will only vest if the grantee is employed by Martin Resource Management Corporation on March 31, 2021. As of March 31, 2019, the Partnership is unable to ascertain if certain performance conditions will be achieved and, as such, has not recognized compensation expense for the vesting of the units. The Partnership will record compensation expense for the vested portion of the units once the achievement of the performance condition is deemed probable.

The restricted units are valued at their fair value at the date of grant which is equal to the market value of common units on such date. A summary of the restricted unit activity for the three months ended March 31, 2019 is provided below:



	Number of Units			Weighted Average Grant-Date Fair Value Per Unit
Non-vested, beginning of period	624,125			$	13.78
Granted (TBRU)	16,944			$	12.45
Vested	(107,762		)	$	13.82
Forfeited	(118,087		)	$	13.90
Non-Vested, end of period	415,220			$	13.77

Aggregate intrinsic value, end of period	$	5,169

A summary of the restricted units’ aggregate intrinsic value (market value at vesting date) and fair value of units vested (market value at date of grant) during the three months ended March 31, 2019 and 2018 is provided below:



	Three Months Ended March 31,
	2019		2018
Aggregate intrinsic value of units vested	$	1,351	$	1,188
Fair value of units vested	1,551		2,232

As of March 31, 2019, there was $2,990 of unrecognized compensation cost related to non-vested restricted units. That cost is expected to be recognized over a weighted-average period of 2.25 years.

NOTE 14. RELATED PARTY TRANSACTIONS

Partnership’s outstanding limited partner units, effectively gives Martin Resource Management Corporation the ability to veto some of the Partnership’s actions and to control the Partnership’s management.

The following is a description of the Partnership’s material related party agreements and transactions:

Omnibus Agreement

Omnibus Agreement. The Partnership and its general partner are parties to the Omnibus Agreement dated November 1, 2002, with Martin Resource Management Corporation 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 the Partnership’s use of certain Martin Resource Management Corporation trade names and trademarks. The Omnibus Agreement was amended on November 25, 2009, to include processing crude oil into finished products including naphthenic lubricants, distillates, asphalt and other intermediate cuts. The Omnibus Agreement was amended further on October 1, 2012, to permit the Partnership to provide certain lubricant packaging products and services to Martin Resource Management Corporation.

Non-Competition Provisions. Martin Resource Management Corporation has agreed for so long as it controls the general partner of the Partnership, not to engage in the business of:


•	providing terminalling and storage services for petroleum products and by-products including the refining, blending and packaging of finished lubricants;

•providing land and marine transportation of petroleum products, by-products, and chemicals;

•distributing NGLs; and

•	any business that Martin Resource Management Corporation acquires or constructs that has a fair market value of less than $5,000;

•

any business that Martin Resource Management Corporation acquires or constructs that has a fair market value of $5,000 or more if the Partnership has been offered the opportunity to purchase the business for fair market value and the Partnership declines to do so with the concurrence of the conflicts committee of the board of directors of the general partner of the Partnership (the "Conflicts Committee"); and

•

any business that Martin Resource Management Corporation acquires or constructs where a portion of such business includes a restricted business and the fair market value of the restricted business is $5,000 or more and represents less than 20% of the aggregate value of the entire business to be acquired or constructed; provided that, following completion of the acquisition or construction, the Partnership will be provided the opportunity to purchase the restricted business.

Services. Under the Omnibus Agreement, Martin Resource Management Corporation provides the Partnership with corporate staff, support services, and administrative services necessary to operate the Partnership’s business. The Omnibus Agreement requires the Partnership to reimburse Martin Resource Management Corporation for all direct expenses it incurs or payments it makes on the Partnership’s behalf or in connection with the operation of the Partnership’s business. There is no monetary limitation on the amount the Partnership is required to reimburse Martin Resource Management Corporation for direct expenses. In addition to the direct expenses, under the Omnibus Agreement, the Partnership is required to reimburse Martin Resource Management Corporation for indirect general and administrative and corporate overhead expenses.

Effective January 1, 2019, through December 31, 2019, the Conflicts Committee approved an annual reimbursement amount for indirect expenses of $16,657. The Partnership reimbursed Martin Resource Management Corporation for $4,164 and $4,104 of indirect expenses for the three months ended March 31, 2019 and 2018, respectively. The Conflicts Committee will review and approve future adjustments in the reimbursement amount for indirect expenses, if any, annually.

These indirect expenses are intended to cover the centralized corporate functions Martin Resource Management Corporation provides for the Partnership, 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 the Partnership shares with Martin Resource Management Corporation retained businesses. The provisions of the Omnibus Agreement regarding Martin Resource Management Corporation’s services will terminate if Martin Resource Management Corporation ceases to control the general partner of the Partnership.

Related Party Transactions. The Omnibus Agreement prohibits the Partnership from entering into any material agreement with Martin Resource Management Corporation without the prior approval of the Conflicts Committee. For purposes of the Omnibus Agreement, the term "material agreements" means any agreement between the Partnership and Martin Resource Management Corporation that requires aggregate annual payments in excess of the then-applicable agreed upon reimbursable amount of indirect general and administrative expenses. Please read "Services" above.

License Provisions. Under the Omnibus Agreement, Martin Resource Management Corporation has granted the Partnership a nontransferable, nonexclusive, royalty-free right and license to use certain of its trade names and marks, as well as the trade names and marks used by some of its affiliates.

Amendment and Termination. The Omnibus Agreement may be amended by written agreement of the parties; provided, however, that it may not be amended without the approval of the Conflicts Committee if such amendment would adversely affect the unitholders. The Omnibus Agreement was first amended on November 25, 2009, to permit the Partnership to provide refining services to Martin Resource Management Corporation. The Omnibus Agreement was amended further on October 1, 2012, to permit the Partnership to provide certain lubricant packaging products and services to Martin Resource Management Corporation. Such amendments were approved by the Conflicts Committee. The Omnibus Agreement, other than the indemnification provisions and the provisions limiting the amount for which the Partnership will reimburse Martin Resource Management Corporation for general and administrative services performed on its behalf, will terminate if the Partnership is no longer an affiliate of Martin Resource Management Corporation.

Master Transportation Services Agreement

Master Transportation Agreement. MTI, a wholly owned subsidiary of the Partnership, is a party to a master transportation services agreement effective January 1, 2019, with certain wholly owned subsidiaries of Martin Resource Management Corporation. Under the agreement, MTI agreed to transport Martin Resource Management Corporation's petroleum products and by-products.

Term and Pricing. The agreement will continue unless either party terminates the agreement by giving at least 30 days' written notice to the other party. These rates are subject to any adjustments which are mutually agreed upon or in accordance with a price index. Additionally, shipping charges are also subject to fuel surcharges determined on a weekly basis in accordance with the U.S. Department of Energy’s national diesel price list.

Indemnification. MTI has agreed to indemnify Martin Resource Management Corporation against all claims arising out of the negligence or willful misconduct of MTI and its officers, employees, agents, representatives and subcontractors. Martin Resource Management Corporation has agreed to indemnify MTI against all claims arising out of the negligence or willful misconduct of Martin Resource Management Corporation and its officers, employees, agents, representatives and subcontractors.

Marine Agreements

Marine Transportation Agreement. The Partnership is a party to a marine transportation agreement effective January 1, 2006, as amended, under which the Partnership provides marine transportation services to Martin Resource Management Corporation on a spot-contract basis at applicable market rates. Effective each January 1, this agreement automatically renews for consecutive one year periods unless either party terminates the agreement by giving written notice to the other party at least 60 days prior to the expiration of the then applicable term. The fees the Partnership charges Martin Resource Management Corporation are based on applicable market rates.

Marine Fuel. The Partnership is a party to an agreement with Martin Resource Management Corporation dated November 1, 2002, under which Martin Resource Management Corporation provides the Partnership with marine fuel from its locations in the Gulf of Mexico at a fixed rate in excess of the Platt’s U.S. Gulf Coast Index for #2 Fuel Oil. Under this agreement, the Partnership agreed to purchase all of its marine fuel requirements that occur in the areas serviced by Martin Resource Management Corporation.

Terminal Services Agreements

Diesel Fuel Terminal Services Agreement. Effective January 1, 2016, the Partnership entered into a second amended and restated terminalling services agreement under which the Partnership provides terminal services to Martin Resource Management Corporation for marine fuel distribution. At such time, the per gallon throughput fee the Partnership charged under this agreement was increased when compared to the previous agreement and may be adjusted annually based on a price index. This agreement was further amended on January 1, 2017 and October 1, 2017 to modify its minimum throughput requirements and throughput fees. This agreement, as amended, expired September 30, 2018 and continued thereafter on a month to month basis until terminated by either party by giving 60 days’ written notice.

Miscellaneous Terminal Services Agreements. The Partnership is currently party to several terminal services agreements and from time to time the Partnership may enter into other terminal service agreements for the purpose of providing terminal services to related parties. Individually, each of these agreements is immaterial but when considered in the aggregate they could be deemed material. These agreements are throughput based with a minimum volume commitment. Generally, the fees due under these agreements are adjusted annually based on a price index.

Other Agreements

Cross Tolling Agreement. The Partnership is a party to an amended and restated tolling agreement with Cross Oil Refining and Marketing, Inc. ("Cross") dated October 28, 2014, under which the Partnership processes crude oil into finished

March 31, 2019

(Unaudited)

products, including naphthenic lubricants, distillates, asphalt and other intermediate cuts for Cross. The tolling agreement expires November 25, 2031. Under this tolling agreement, Cross agreed to process a minimum of 6,500 barrels per day of crude oil at the facility at a fixed price per barrel. Any additional barrels are processed at a modified price per barrel. In addition, Cross agreed to pay a monthly reservation fee and a periodic fuel surcharge fee based on certain parameters specified in the tolling agreement. All of these fees (other than the fuel surcharge) are subject to escalation annually based upon the greater of 3% or the increase in the Consumer Price Index for a specified annual period. In addition, on the third, sixth and ninth anniversaries of the agreement, the parties can negotiate an upward or downward adjustment in the fees subject to their mutual agreement.

Sulfuric Acid Sales Agency Agreement. The Partnership was previously a party to a third amended and restated sulfuric acid sales agency agreement dated August 2, 2017 but effective October 1, 2017, under which a successor in interest to the agreement from Martin Resource Management Corporation, Saconix LLC ("Saconix"), a limited liability company in which Martin Resource Management Corporation held a minority equity interest, purchased and marketed the sulfuric acid produced by the Partnership’s sulfuric acid production plant at Plainview, Texas, that was not consumed by the Partnership’s internal operations. This agreement, as amended, was to remain in place until September 30, 2020 and automatically renew year to year thereafter until either party provided 90 days’ written notice of termination prior to the expiration of the then existing term. Under this agreement, the Partnership sold all of its excess sulfuric acid to Saconix, who then marketed and sold such acid to third-parties. The Partnership shared in the profit of such sales. Effective May 31, 2018, Martin Resource Management Corporation no longer holds an equity interest in Saconix. These transactions are reported below as related party transactions during the period the equity interest was held. Transactions subsequent to Martin Resource Management Corporation's disposition of the equity interest will be reported as third party transactions.

Other Miscellaneous Agreements. From time to time the Partnership enters into other miscellaneous agreements with Martin Resource Management Corporation for the provision of other services or the purchase of other goods.

The Partnership’s reportable segments are strategic business units that offer different products and services. The operating income of these segments is reviewed by the chief operating decision maker to assess performance and make business decisions.

The accounting policies of the operating segments are the same as those described in Note 2 in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC on February 19, 2019. The Partnership evaluates the performance of its reportable segments based on operating income. There is no allocation of administrative expenses or interest expense.

NOTE 16. 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. If the case is reopened, we are currently unable to determine the exposure we may have in this matter, if any.

NOTE 17. 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:



	Level 2
	March 31, 2019		December 31, 2018
Commodity derivative contracts, net	$	150	$	4

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 notes is considered Level 1, as the fair value is based on quoted market prices in active markets.



	March 31, 2019				December 31, 2018
	Carrying Value		Fair Value		Carrying Value		Fair Value
2021 Senior unsecured notes	$	373,090	$	369,560	$	372,996	$	360,138

NOTE 18. CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The Partnership's operations are conducted by its operating subsidiaries as it has no independent assets or operations. Martin Operating Partnership L.P. (the "Operating Partnership"), the Partnership’s wholly-owned subsidiary, and the Partnership's other operating subsidiaries have issued in the past, and may issue in the future, unconditional guarantees of senior or subordinated debt securities of the Partnership. The guarantees that have been issued are full, irrevocable and unconditional and joint and several. In addition, the Operating Partnership may also issue senior or subordinated debt securities which, if issued, will be fully, irrevocably and unconditionally guaranteed by the Partnership. Substantially all of the Partnership's

operating subsidiaries are subsidiary guarantors of its outstanding senior unsecured notes and any subsidiaries other than the subsidiary guarantors are minor.

NOTE 19. INCOME TAXES



	Three Months Ended March 31,
	2019		2018
Provision for income taxes	$	696	$	149

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 (benefit) of $448 and $0, related to the operation of the subsidiary, for the three months ended March 31, 2019 and 2018, respectively, resulted in an effective income tax rate of 24.79% and 0%, respectively. The increase in the effective income tax rate and provision for income taxes during the three months ended March 31, 2019, compared to March 31, 2018, is primarily due to a change in MTI’s tax status from a non-taxable Qualified Subchapter S subsidiary (“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 into its S Corporation parent. S Corporations are generally not subject to income 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 $297 and $0 and a current state income tax expense (benefit) of $(218) and $0, related to the operation of the subsidiary were recorded for the three months ended March 31, 2019 and 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.

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 $369 and $0 was recorded for the three months ended March 31, 2019 and 2018, respectively. A deferred tax asset of $24,412 and $0, related to the cumulative book and tax temporary differences, existed at March 31, 2019 and December 31, 2018, 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.

NOTE 20. SUBSEQUENT EVENTS

Quarterly Distribution. On April 24, 2019, the Partnership declared a quarterly cash distribution of $0.25 per common unit for the first quarter of 2019, or $1.00 per common unit on an annualized basis, which will be paid on May 15, 2019 to unitholders of record as of May 8, 2019.

Credit Facility Amendment. On April 16, 2019, the Partnership amended it's revolving credit facility to, among other things, reduce commitments from $664,444 to $500,000 and to adjust the permitted Leverage Ratio (as defined in the credit agreement) to 5.85 times for the fiscal quarters ended March 31, 2019 and June 30, 2019.



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:


•	Natural gas liquids transportation and distribution services and natural gas storage;


•	Terminalling and storage services for petroleum products and by-products including the refining of naphthenic crude oil and the blending and packaging of finished lubricants;


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


•	Transportation services for petroleum products and by-products.

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 March 31, 2019, 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 services business in the 1950s and our sulfur business in the 1960s. It began our marine transportation business in the late 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

Martin Transport Inc. Stock Purchase Agreement. On October 22, 2018, we entered into a stock purchase agreement (the “Stock Purchase Agreement”) with Martin Resource Management Corporation to acquire all of the issued and outstanding equity 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 finalized on January 28, 2019 which included additional consideration paid 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 integral to 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.

Subsequent Events

Quarterly Distribution. On April 24, 2019, we declared a quarterly cash distribution of $0.25 per common unit for the first quarter of 2019, or $1.00 per common unit on an annualized basis, which will be paid on May 15, 2019 to unitholders of record as of May 8, 2019.

Credit Facility Amendment. On April 16, 2019 the Partnership amended it's revolving credit facility to, among other things, reduce commitments from $664.4 million to $500.0 million and to adjust the permitted Leverage Ratio (as defined in the credit agreement) to 5.85 times for the fiscal quarters ended March 31, 2019 and June 30, 2019.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on the historical consolidated and condensed financial statements included elsewhere herein. We prepared these financial statements in conformity with United States generally accepted accounting principles ("U.S. GAAP" or "GAAP"). The preparation of these financial statements requires 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 base 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. See the "Critical Accounting Policies and Estimates" section in "Managements Discussion and Analysis of Financial Condition and Results of Operations" and Note 2, "Significant Accounting Policies" in Notes to Consolidated Financial Statements included within our Annual Report on Form 10-K for the year ended December 31, 2018.

Approval and Review of Related Party Transactions

If we contemplate entering into a transaction, other than a routine or in the ordinary course of business transaction, in which a related person will have a direct or indirect material interest, the proposed transaction is submitted for consideration to the board of directors of our general partner or to our management, as appropriate. If the board of directors of our general partner is involved in the approval process, it determines whether to refer the matter to the Conflicts Committee of our general partner's board of directors, as constituted under our limited partnership agreement. If a matter is referred to the Conflicts Committee, it obtains information regarding the proposed transaction from management and determines whether to engage

independent legal counsel or an independent financial advisor to advise the members of the committee regarding the transaction. If the Conflicts Committee retains such counsel or financial advisor, it considers such advice and, in the case of a financial advisor, such advisor’s opinion as to whether the transaction is fair and reasonable to us and to our unitholders.

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 months ended March 31, 2019 and 2018.

Results of Operations

The results of operations for the three months ended March 31, 2019 and 2018 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 months ended March 31, 2019 and 2018. 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.

Services revenues. Services revenue decreased $0.7 million, of which $0.4 million was a result of the disposition of our sulfuric acid terminal in Elko, Nevada. In addition, $0.4 million was a result of decreased throughput at our Tampa specialty terminal.

Products revenues. A 31% decrease in sales volumes combined with a 20% decrease in average sales price at our shore based terminals resulting in an $8.4 million decrease in products revenues. Offsetting this decrease was a 12% increase in sales volumes combined with a 5% increase in average sales price at our blending and packaging facilities resulting in a $3.2 million increase to products revenues.

Cost of products sold. A 31% decrease in sales volumes combined with a 20% decrease in average sales price at our shore based terminals resulting in a $7.8 million decrease in cost of products sold. Offsetting this decrease was a 12% increase in sales volumes combined with a 6% increase in average cost per gallon at our blending and packaging facilities resulting in a $2.7 million increase in cost of products sold.

Operating expenses. Operating expenses remained relatively consistent.

Selling, general and administrative expenses. Selling, general and administrative expenses remained relatively consistent.

Depreciation and amortization. The decrease in depreciation and amortization is due to the disposition of assets at several closed shore-based facilities and our sulfuric acid terminal in Elko, Nevada, offset by recent capital expenditures.

Other operating income. Other operating income represents losses from the disposition of property, plant and equipment.

Services Revenues. The decrease in services revenue is primarily a result of lower firm storage re-contracting rates at our Perryville gas storage facility.

Products Revenues. Our average sales price per barrel decreased $6.19, or 13%, resulting in a decrease to products revenues of $21.3 million. The decrease in average sales price per barrel was a result of a decrease in market prices. Product sales volumes decreased 15%, decreasing products revenues by $21.4 million.

Cost of products sold. Our average cost per barrel decreased $3.49, or 8%, decreasing cost of products sold by $12.0 million. The decrease in average cost per barrel was a result of a decrease in market prices. The decrease in sales volume of 15% resulted in a $20.4 million decrease to cost of products sold. Our margins decreased $2.70 per barrel, or 60%, during the period.

Operating expenses. Operating expenses increased $0.7 million at our natural gas storage facilities, primarily as a result of an increase of $0.7 million in expense for pressure support, $0.2 million in supplies and maintenance and $0.1 million in insurance premium related expense. These increases are offset by $0.2 million in decreased utility expense and $0.1 million in decreased employee expense.

Selling, general and administrative expenses. Selling, general and administrative expenses decreased primarily due to decreased compensation expense.

Depreciation and amortization. Depreciation and amortization decreased $0.6 million primarily due to a decrease in amortization related to contracts acquired as part of the purchase of Cardinal.

Other operating income. Other operating income represents gains from the disposition of property, plant and equipment.

Services revenues. Services revenues increased $0.1 million as a result of renegotiation of contract terms effective January 2019.

Products revenues. Products revenue decreased $14.4 million as a result of a 33% decline in sales volumes, primarily attributable to a 38% decrease in sulfur volumes. A 23% increase in average sales price resulted in an offsetting increase of $8.2 million.

Cost of products sold. A 33% decrease in sales volumes reduced our cost of products sold by $10.8 million. Offsetting this decrease was an increase in cost of products sold of $8.4 million as a result of a 35% increase in average cost of products sold per ton. Margin per ton decreased $0.61, or 1%.

Operating expenses. Our operating expenses decreased primarily as a result of a $0.4 million reduction in marine fuel and lube and $0.2 million in lower repairs and maintenance of marine vessels. An additional combined decrease of $0.1 million is due to a reduction in leases and other marine operating expenses.

Selling, general and administrative expenses. Selling, general and administrative expenses increased $0.1 million due to increased compensation expense.

Depreciation and amortization. Increased as a result of recent capital expenditures.

Other operating loss. Other operating loss represents losses from the disposition of property, plant and equipment.

Marine Transportation Revenues. An increase of $2.9 million in inland revenue is attributable to increased utilization and additional leased equipment being placed in service. Offsetting this increase, offshore revenue decreased $0.5 million primarily due to equipment being down for regulatory inspections and maintenance.

Land Transportation Revenues. Freight revenue increased $0.7 million. Transportation rates increased 9% resulting in an increase to freight revenue of $2.2 million. Miles decreased 5% resulting in an offsetting decrease of $1.5 million.

Operating expenses. The decrease in operating expenses is primarily a result of decreased lease expense of $1.5 million. This decrease was offset by increases in outside towing of $0.9 million, and repair and maintenance of $0.4 million.

Selling, general and administrative expenses. Selling, general and administrative expenses increased primarily due to the reclassification of expenses from operating expense to selling, general and administration expense of $0.5 million.

Depreciation and amortization. Depreciation and amortization increased as a result of recent capital expenditures offset by asset disposals.

Other operating loss. Other operating loss represents losses from the disposition of property, plant and equipment.

Indirect Selling, General and Administrative Expenses

	2019		2018		Variance		Percent Change
	(In thousands)
Indirect selling, general and administrative expenses	$	4,567	$	4,231	$	336	8	%

Indirect selling, general and administrative expenses increased for the three months ended March 31, 2019 compared to the three months ended March 31, 2018 primarily due to increased unit based compensation expense of $0.2 million.

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

Under the Omnibus Agreement, we are required to reimburse Martin Resource Management Corporation for indirect general and administrative and corporate overhead expenses. The Conflicts Committee of our general partner approved the following reimbursement amounts during the three months ended March 31, 2019 and 2018:

The amounts reflected above represent our allocable share of such expenses. The Conflicts Committee will review and approve future adjustments in the reimbursement amount for indirect expenses, if any, annually.

Liquidity and Capital Resources

General

Our primary sources of liquidity to meet operating expenses, pay distributions to our unitholders and fund capital expenditures have historically been cash flows generated by our operations and access to debt and equity markets, both public and private. Management believes that expenditures for 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

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.

Cash Flows - Three Months Ended March 31, 2019 Compared to Three Months Ended March 31, 2018

The following table details the cash flow changes between the three months ended March 31, 2019 and 2018:



	Three Months Ended March 31,						Variance			Percent Change
	2019			2018			Variance			Percent Change
	(In thousands)
Net cash provided by (used in):
Operating activities	$	40,603		$	59,329		$	(18,726	)	(32	)%
Investing activities	(33,946		)	(18,328		)	(15,618		)	(85	)%
Financing activities	(6,730		)	(40,844		)	34,114			84	%
Net increase (decrease) in cash and cash equivalents	$	(73	)	$	157		$	(230	)	(146	)%

Net cash provided by operating activities. The decrease in net cash provided by operating activities for the three months ended March 31, 2019 includes a decrease in operating results of $17.2 million and an unfavorable variance in other non-current assets and liabilities of $1.4 million. Net cash received from discontinued operating activities decreased $1.4 million. Offsetting was a $0.9 million favorable variance in working capital and a $0.4 million increase in other non-cash charges.

Net cash used in investing activities. Net cash used in investing activities for the three months ended March 31, 2019 increased primarily as a result of $23.7 million in net assets acquired from MTI. Offsetting was a $0.6 million increase in proceeds received as a result of higher sales of property, plant and equipment in 2019, as well as, an increase of $5.8 million due to lower payments for capital expenditures and plant turnaround costs in 2019. Net cash used in discontinued investing activities decreased $1.7 million.

Net cash provided by financing activities. Net cash provided by financing activities increased for the three months ended March 31, 2019 as a result of an increase in net proceeds of long-term borrowings of $133.0 million as well as a decrease in costs associated with our credit facility amendment of $1.2 million. Also contributing was a $2.3 million increase related to the 2018 period including a preacquisition distribution to Martin Resource Management Corporation. Offsetting was an increase in cash used of $102.4 million related to excess purchase price over the carrying value of acquired assets in common control transactions.

Capital Resources

Historically, we have generally satisfied our working capital requirements and funded our capital expenditures with cash generated from operations and borrowings. We expect our primary sources of funds for short-term liquidity will be cash flows from operations and borrowings under our credit facility.

Total Contractual Cash Obligations. A summary of our total contractual cash obligations as of March 31, 2019, is as follows:



	Payments due by period
Type of Obligation	Total Obligation		Less than One Year		1-3 Years		3-5 Years		Due Thereafter
Revolving credit facility	$	404,000	$	404,000	$	—	$	—	$	—
2021 Senior unsecured notes	373,800		—		373,800		—		—

Total contractual cash obligations	$	887,341	$	453,321	$	421,988	$	4,455	$	7,577

The interest payable under our credit facility is not reflected in the above table because such amounts depend on the outstanding balances and interest rates, which vary from time to time.

Letters of Credit. At March 31, 2019, we had outstanding irrevocable letters of credit in the amount of $16.9 million, which were issued under our revolving credit facility.

Off Balance Sheet Arrangements. We do not have any off-balance sheet financing arrangements.

Description of Our Long-Term Debt

2021 Senior Notes

For a description of our 7.25% senior unsecured notes due 2021, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Description of Our Long-Term Debt" in our Annual Report on Form 10-K for the year ended December 31, 2018.

Revolving Credit Facility

At March 31, 2019, we maintained a $664.4 million credit facility. This facility was most recently amended on April 16, 2019 to, among other things, reduce commitments from $664.4 million to $500.0 million and to adjust the permitted Leverage Ratio (as defined in the credit agreement) to 5.85 times for the fiscal quarters ended March 31, 2019 and June 30, 2019 and 5.50 times for the fiscal quarter ending September 30, 2019.

As of March 31, 2019, we had $404.0 million outstanding under the revolving credit facility leaving a maximum available to be borrowed under our credit facility for future revolving credit borrowings and letters of credit of $260.4 million. Subject to the financial covenants contained in our credit facility and based on our existing EBITDA (as defined in our credit facility) calculations, as of March 31, 2019, we have the ability to borrow approximately $47.5 million of that amount.

The revolving credit facility is used for ongoing working capital needs and general partnership purposes, and to finance permitted investments, acquisitions and capital expenditures. During the three months ended March 31, 2019, the level of outstanding draws on our credit facility has ranged from a low of $287.0 million to a high of $433.5 million.

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

We may prepay all amounts outstanding under the credit facility at any time without premium or penalty (other than customary LIBOR breakage costs), subject to certain notice requirements. The credit facility requires mandatory prepayments of amounts outstanding thereunder with the net proceeds of certain asset sales, equity issuances and debt incurrences.

Indebtedness under the credit facility bears interest at our option at the Eurodollar Rate (the British Bankers Association LIBOR Rate) plus an applicable margin or the Base Rate (the highest of the Federal Funds Rate plus 0.50%, the 30-day Eurodollar Rate plus 1.0%, or the administrative agent’s prime rate) plus an applicable margin. We pay a per annum fee on all letters of credit issued under the credit facility, and we pay a commitment fee per annum on the unused revolving credit availability under the credit facility. The letter of credit fee, the commitment fee and the applicable margins for our interest rate vary quarterly based on our leverage ratio (as defined in the credit facility, being generally computed as the ratio of total funded debt to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges) and are as follows as of March 31, 2019:



Leverage Ratio	Base Rate Loans		Eurodollar Rate Loans		Letters of Credit
Less than 3.00 to 1.00	1.00	%	2.00	%	2.00	%
Greater than or equal to 3.00 to 1.00 and less than 3.50 to 1.00	1.25	%	2.25	%	2.25	%
Greater than or equal to 3.50 to 1.00 and less than 4.00 to 1.00	1.50	%	2.50	%	2.50	%
Greater than or equal to 4.00 to 1.00 and less than 4.50 to 1.00	1.75	%	2.75	%	2.75	%
Greater than or equal to 4.50 to 1.00	2.00	%	3.00	%	3.00	%

At March 31, 2019, the applicable margin for revolving loans that are LIBOR loans ranges from 2.00% to 3.00% and the applicable margin for revolving loans that are base prime rate loans ranges from 1.00% to 2.00%. The applicable margin for LIBOR borrowings at March 31, 2019 is 3.00%.

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

In addition, the credit facility contains various covenants, which, among other things, limit our and our subsidiaries’ ability to: (i) grant or assume liens; (ii) make investments (including investments in our joint ventures) and acquisitions; (iii) enter into certain types of hedging agreements; (iv) incur or assume indebtedness; (v) sell, transfer, assign or convey assets; (vi) repurchase our equity, make distributions and certain other restricted payments, but the credit facility permits us 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.

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 March 31, 2019 and expect to be in compliance for the next twelve months.

Seasonality

A substantial portion of our revenues are 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 natural gas storage division of the Natural Gas Services segment provides stable cash flows and is not generally subject to seasonal demand factors. Additionally, our Terminalling and Storage and Transportation 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 and transportation businesses. Therefore, we do not expect that our overall net income will be impacted by seasonality factors. However, extraordinary weather events, such as hurricanes, have in the past, and could in the future, impact our Terminalling and Storage and Transportation segments.

Impact of Inflation

Inflation did not have a material impact on our results of operations for the three months ended March 31, 2019 or 2018. Although the impact of inflation has been insignificant in recent years, it is still a factor in the U.S. economy and may increase the cost to acquire or replace property, plant and equipment. It may also increase the costs of labor and supplies. In the future, increasing energy prices could adversely affect our results of operations. Diesel fuel, natural gas, chemicals and other supplies are recorded in operating expenses. An increase in price of these products would increase our operating expenses which could adversely affect net income. We cannot provide assurance that we will be able to pass along increased operating expenses to our customers.

Environmental Matters

Our operations are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which these operations are conducted. We incurred no material environmental costs, liabilities or expenditures to mitigate or eliminate environmental contamination during the three months ended March 31, 2019 or 2018.



Item 3.	Quantitative and Qualitative Disclosures about Market Risk

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

We have entered into hedging transactions as of March 31, 2019 to protect a portion of our commodity price risk exposure. These hedging arrangements are in the form of swaps for NGLs. We have instruments totaling a gross notional quantity of 472,000 barrels settling during the period from April 1, 2019 through September 30, 2019. These instruments settle against the applicable pricing source for each grade and location. These instruments are recorded on our Consolidated and Condensed Balance Sheets at March 31, 2019 in "Fair value of derivatives" as a current asset of $0.2 million. Based on the current net notional volume hedged as of March 31, 2019, a $0.10 change in the expected settlement price of these contracts would result in an impact to our net income of approximately $2.0 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 5.49% as of March 31, 2019. Based on the amount of unhedged floating rate debt owed by us on March 31, 2019, 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 $4.0 million annually.

We are not exposed to changes in interest rates with respect to our senior unsecured notes as these obligations are fixed rate. The estimated fair value of the senior unsecured notes was approximately $369.6 million as of March 31, 2019, based on market prices of similar debt at March 31, 2019. 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 $6.3 million decrease in the fair value of our long-term debt at March 31, 2019.



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 16 in Part I of this Form 10-Q.



Item 1A.	Risk Factors

There have been no material changes to the risk factors disclosed in our annual report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission (the "SEC") on February 19, 2019.
